Adding pockets to a garment is a transformative tailoring skill that elevates both functionality and style. This guide provides a comprehensive, practical, and step-by-step approach to seamlessly integrating a variety of pocket types into your clothing. From the foundational patch pocket to the intricate welt pocket, we’ll demystify each process, ensuring you can confidently customize your wardrobe with professional-quality results.
The Foundation: Essential Tools and Fabric Prep
Before you begin, gather your tools. Having the right equipment makes all the difference in achieving a clean, professional finish. You will need:
- Fabric Scissors: Sharp, dedicated shears for cutting fabric.
-
Rotary Cutter and Mat: Excellent for cutting straight lines and multiple layers accurately.
-
Sewing Machine: A basic machine with a straight stitch and a zigzag stitch is sufficient.
-
Iron and Ironing Board: Crucial for pressing seams, which is the secret to a polished look.
-
Pins or Wonder Clips: To hold fabric pieces together.
-
Hand-sewing Needles: For any delicate finishing touches.
-
Thread: Matching or contrasting, depending on your design.
-
Measuring Tape or Ruler: For precise measurements.
-
Tailor’s Chalk or Fabric Pen: To mark your cutting and sewing lines.
-
Seam Ripper: For fixing mistakes (it happens to everyone!).
-
Interfacing: A non-woven fabric used to add structure and stability.
Fabric Preparation: Always pre-wash your fabric the same way you plan to wash the finished garment. This prevents future shrinkage and distortion. Press the fabric thoroughly before cutting to ensure a smooth, wrinkle-free surface.
Part 1: The Classic Patch Pocket
The patch pocket is the simplest and most common type, ideal for beginners. It’s a piece of fabric sewn directly onto the exterior of a garment.
Step 1: Pattern and Cutting
Decide on the size and shape of your pocket. A good rule of thumb for a standard shirt pocket is 5 inches wide by 5.5 inches tall. Add seam allowances:
- Add 1/2 inch to the sides and bottom.
-
Add 1 to 1.5 inches to the top for the hem.
For a 5″ x 5.5″ pocket, your cutting dimensions would be 6″ wide x 7.5″ tall. Cut a rectangle of fabric using these dimensions.
Step 2: Creating the Hem
Fold the top edge of the pocket piece down by 1/4 inch and press. Fold it down another 3/4 inch and press again. This creates a clean, durable hem. Stitch along the bottom edge of this fold, 1/8 inch from the edge. This secures the hem.
Step 3: Finishing the Raw Edges
Fold and press the remaining three raw edges (sides and bottom) of the pocket piece inwards by 1/2 inch. This hides the raw edges and creates the lines you will follow for sewing.
Step 4: Positioning and Attaching the Pocket
Measure and mark the exact placement of the pocket on your garment. For a shirt, a common placement is approximately 2.5 inches down from the shoulder seam and 2.5 inches in from the center front. Use pins to secure the pocket in place, making sure it’s perfectly level.
Step 5: Sewing the Pocket
Starting at the top corner of one side, stitch 1/8 inch from the folded edge, all the way down, across the bottom, and up the other side. Reinforce the top corners with a small triangle or backstitch to prevent tearing. This is a high-stress point, so reinforcement is key. Remove the pins and give the pocket a final press.
Part 2: The In-Seam Pocket
The in-seam pocket is a hidden pocket sewn into a garment’s side seam, offering a clean, discreet look. This is a perfect addition to skirts, dresses, or trousers.
Step 1: Creating the Pocket Bag Pattern
Draw a pocket bag pattern. A standard size is a rounded rectangle, about 6 inches wide and 8 inches tall. Create two identical pieces for each pocket. This will be the pocket bag.
Step 2: Preparing the Garment and Pocket Bag
Pin one pocket bag piece to the right side of the front garment panel, aligning the straight edge of the pocket bag with the side seam of the garment. The pocket bag should be placed where you want the opening to be, typically a few inches below the waistline. Sew the pocket bag to the garment panel with a 1/2-inch seam allowance.
Repeat this process for the back garment panel with the second pocket bag piece.
Step 3: Sewing the Seam and Pocket Opening
Place the front and back garment panels right sides together. Pin along the side seam. The pocket bags should be sandwiched inside.
Sew down the side seam, stopping at the top of the pocket opening. Backstitch to secure the thread. Continue sewing around the entire curved edge of the pocket bag. Once you’ve sewn around the pocket bag, resume sewing the side seam of the garment, starting from the bottom of the pocket opening down to the hem.
Step 4: Finishing Touches
Clip the curves of the pocket bag to reduce bulk. Turn the garment right side out and press the entire seam and pocket area. Topstitch along the side seam and around the pocket opening if desired, to further secure the pocket and create a professional finish.
Part 3: The J-Pocket or Slant Pocket
Commonly found on trousers, jeans, and casual jackets, the J-pocket features a diagonal opening. This pocket requires a bit more precision.
Step 1: Cutting the Pattern Pieces
You will need three pieces of fabric for each pocket:
- The Main Pocket Bag (Front): A piece of fabric that will form the front of the pocket.
-
The Under Pocket Bag (Back): A piece that forms the back of the pocket.
-
The Pocket Facing: A small piece of fabric, often cut from the main garment fabric, that will create the finished edge of the pocket opening.
Draw a pattern for the pocket opening on the front garment panel. A good starting point is a diagonal line approximately 5 inches long, starting 1.5 inches down from the waistband and 1.5 inches in from the side seam. Cut along this line.
Step 2: Assembling the Pocket Opening
Pin the pocket facing piece to the slanted edge of the front garment panel, right sides together. Sew with a 1/4-inch seam allowance. Press the seam allowance towards the facing.
Turn the garment panel over so the facing is on the inside. Understitch the seam allowance to the facing to prevent it from rolling to the outside. Topstitch along the slanted edge of the pocket opening if desired.
Step 3: Sewing the Pocket Bag
Place the main pocket bag piece (which will be visible on the inside) underneath the garment panel, aligning the top and side edges. Pin the under pocket bag piece to the backside of the garment panel.
Sew the two pocket bag pieces together along the curved bottom and side edges. Make sure you are only sewing the pocket bag pieces and not the garment itself.
Step 4: Attaching to the Garment
Now, pin the side seams of the front and back garment panels together, sandwiching the pocket inside. Sew the entire side seam, catching the pocket bag pieces securely in the seam. This will hold the pocket in place. Finish the seam with a serger or a zigzag stitch to prevent fraying.
Part 4: The Advanced Welt Pocket
A welt pocket is a horizontal, slit-style pocket with a narrow fabric strip, or welt, forming the opening. This technique is often seen on formal trousers, vests, and jackets. It is the most challenging of the pocket types.
Step 1: Preparing the Pieces
You will need two pocket bag pieces and a welt strip.
- The Pocket Bags: Two rectangular pieces, one for the top and one for the bottom of the pocket.
-
The Welt Strip: A rectangular strip of fabric. A common size is 2 inches wide by 6 inches long. Fuse a lightweight interfacing to the back of the welt strip to add stability.
Mark the exact placement of the pocket on the garment with a rectangle using tailor’s chalk. For a 5-inch pocket opening, draw a rectangle that is 5 inches wide and 1/2 inch tall. Draw a centerline through the rectangle.
Step 2: Attaching the Welt Strip
Place the welt strip right side down on the garment, centered over the marked rectangle. The bottom edge of the welt strip should be aligned with the top line of the rectangle. Sew the welt strip to the garment with a 1/4-inch seam allowance, using the bottom line of the marked rectangle as your stitching guide.
Step 3: Attaching the Top Pocket Bag
Place the top pocket bag piece right side down on the garment, with its top edge aligned with the top line of the marked rectangle. Sew along this top line, using a 1/4-inch seam allowance.
Step 4: Slitting the Pocket and Turning
Carefully cut through the center of the marked rectangle, from one end to the other. Stop 1/2 inch from each end, and then clip diagonally to the corners of the stitching lines, creating a “Y” shape at each end. Be careful not to clip the stitches.
Push the pocket bag pieces and the welt strip through the slit to the inside of the garment. Pull them taught and press everything flat.
Step 5: Forming the Welt
On the inside of the garment, fold the welt strip up so it covers the opening. It should form a clean, narrow lip. The top pocket bag piece will now be on the inside, and the bottom pocket bag piece and the turned welt strip will form the pocket.
Sew the triangles you created at the ends of the slit to the welt and the pocket bags. This will secure the corners of the pocket opening.
Step 6: Finishing the Pocket Bag
Turn the garment inside out. Pin the two pocket bag pieces together, making sure they are aligned. Sew around the three open sides of the pocket bag to close it. Finish the raw edges with a serger or a zigzag stitch.
Expert Tailoring Tips for Flawless Pockets
- Press, Press, Press: Pressing is non-negotiable. After every single stitch, press your seams. It sets the stitches, sharpens folds, and gives a professional, crisp finish.
-
Use the Right Thread: Use a high-quality all-purpose polyester thread. It’s strong and doesn’t fray easily. Match the thread to your fabric for a seamless look, or choose a contrasting color for a design element.
-
Reinforce High-Stress Points: Always backstitch at the beginning and end of seams, especially on pockets, as they will be under constant stress from hands and objects. Reinforce corners on patch pockets with a small triangle or box stitch.
-
Test on Scrap Fabric: Before you cut into your final garment, practice on a piece of scrap fabric. This allows you to perfect your technique and check your thread tension.
-
Stabilize with Interfacing: For welt pockets and other structured pocket openings, always use a lightweight fusible interfacing on the garment area and the pocket facing. This prevents stretching and gives the pocket a clean, stable look.
-
Take Your Time: Don’t rush. Precision is key in tailoring. Measure twice, cut once. Pin carefully and sew slowly. The extra time you take will result in a significantly better outcome.
