In today's tutorial, I'm going to show you how to sew a fanny pack or crossbody bag. I made the DIY fanny pack pattern myself, and I'll give you all the instructions for that.

Go slowly when sewing through multiple layers of this fabric. Use a needle suitable for heavyweight fabric and feed the fabric through your machine manually where necessary.

Tools and materials:

  • Tracing paper for pattern
  • Laminated fabric
  • Two way (double) zipper
  • Webbing strap
  • Plastic buckle lock
  • 1" Fold over elastic
  • Bias tape (optional)
  • Ruler
  • Pencil
  • Fabric marker
  • Fabric clips
  • Pins
  • Sewing machine
  • Needle size 16 (100)
  • Zipper foot
Drafting the pattern

1. Draft the pattern

Watch the video from 0:16 to 1:45 to see exactly how I draft the pattern pieces and how many of each to cut.

Cut-out fabric pieces

2. Cut out the fabric pieces

Cut out the pattern pieces and mark their names on the back. Also mark a half inch (1 cm) seam allowance on each piece.

Adding the pocket

3. Add the pocket

Fold in the top edge of the pocket and sew in place on the right side with two rows of stitching.

Adding the pocket

Place the pocket on the back section, with the wrong side of the pocket to the right side of the back.

Mark the center of the pocket. Sew the pieces together around the three lower edges inside the seam allowance.

Sew a line of stitches down the center of the pocket to make two separate sections. Trim off the excess fabric.

Inserting the zipper

4. Insert the zipper

Mark the center points of the zipper, the upper front edge and the flap.

Pin the curved edge of the flap to the upper edge of the zipper, matching the centers.

Sew with a zipper foot close to the teeth, stitching from the center to the end on both sides.

Inserting the zipper

Open the zipper and pin the other side of the zipper tape to the front section, matching the center points.

Sew as close to the teeth as you can, again sewing from the center to each end.

Attaching the base

5. Attach the base

Pin the curved edge of the bottom section to the lower edge of the front, with right sides facing, and sew in place. Trim the excess fabric. 

Binding the seams

6. Bind the seams

Pin fold over elastic (unstretched) or bias tape over the bottom seam, enclosing the raw edge. 

Fold the free edges of the zipper tape over the raw edges of the flap and front seams and pin.

Binding the seams

Sew the bindings in place carefully through all layers.

Cut off the excess zipper tape.

Attaching the sides

7. Attach the sides

Pin the straight edge of the side section to the edge of the front with right sides together, so it covers the end of the zipper and the binding on the lower edge. 

Attaching the sides

Trim off the excess fabric and bind the seams as before.

Making the adjustable strap

8. Make the adjustable strap

Cut your webbing strap into two equal lengths. Cut two pieces of elastic to wrap around the strap, unstretched, plus a seam allowance. 

Making the adjustable strap

Sew along the seam allowance of each elastic piece, open the seam and stitch down the edges. 

Making the adjustable strap

Slide one elastic loop over each strap. Thread each strap through one side of the buckle lock and under the elastic. 

Making the adjustable strap

Turn the short end of the strap over twice and sew securely around the edges and across the diagonals.

Attaching the straps

9. Attach the straps

Pin and sew the raw edge of each strap to the outer edge of the side section, so that the straps face inwards across the front of the bag.

Attaching the back

10. Attach the back

Place the back section over the assembled bag, with right sides facing.

Matching the center points at the flap and base, pin and sew the back in place around all edges.

Attaching the back

Cut off the excess seam allowances and bind all the seams as before.

Turn the bag right side out through the open zipper.

Attaching the back

I really had a lot of fun with this fanny pack DIY. I used a laminated fabric for shape and durability but you can use any similar weight fabric that will hold its shape well.

You can adjust the length of the straps to make a crossbody bag or a shoulder bag, as well as a fanny pack.

I would love to know if you make this - please leave a comment below if you do.
