To make:
Use a 13 mm (1/2-in) seam allowance throughout unless otherwise indicated. Decide which side of quilted fabric you want to have showing on outside of bag. This will be the right side. The other side will be the reverse side.

1. From quilted fabric, cut pieces according to cutting diagram. Mark pleat lines on pockets by measuring 21 cm from each side toward centre of pocket. Mark placement of handles.

2. Outside: Press under 1.3 cm along zipper edge of one outside upper pocket and along one 56 cm edge of outside lower pocket. Centre one 55 cm zipper between these edges and topstitch in place. Attach second 55 cm zipper to remaining upper pocket and opposite edge of lower pocket. When this piece is folded down centre fold line, it will form the 2 outer sides of the bag.

3. Handles: Fold each handle in half so long edges meet and right sides are together. Stitch long edges together. Turn right side out. Press. Turn under 1.3 cm at both ends of each handle. Position ends of one handle just above zipper on one upper pocket as indicated on diagram. Topstitch ends in place securely by stitching a small square through all layers. Repeat with second handle on other upper pocket.

4. Inside pockets: Cut a piece of binding to fit along one long edge of diaper pocket. Repeat for tissue pocket and bottle pocket. Encase edge of fabric in fold of binding. Edgestitch close to inner edge of binding, making sure to catch underside of binding in stitching. The bound edge is the top edge of each pocket.

5. With reverse side of fabric facing, pleat each pocket as indicated on diagram by folding broken line in direction of arrows to meet dotted line. Baste pleats along bottom edge of each pocket.
With reverse sides together and edges even, sew diaper pocket to tissue pocket at sides, then tissue pocket to bottle pocket. Press seams open.

6. With reverse side of pleated pocket section and right side of inside bag piece together, place bottom edge of pocket section so it overlaps centre fold line of inside bag by 1.3 cm. Stitch pieces together along centre fold line. Fold pocket section back in direction of seam allowance; baste side edges to side of bag.

Topstitch down seamlines where pockets join each other and down centre of bottle pocket to make 2 small bottle compartments.

7. With wrong sides together, pin inside to outside bag; baste around all edges. Topstitch layers together along centre fold line.

8. Pin remaining binding around basted edges of bag, encasing raw edges in fold of binding. Cut off any excess binding. Edgestitch close to inner edge of binding.

9. Separating zippers: With right side of zipper tape and inside of bag together, and starting with bottom of zipper at centre fold line, baste one side of one zipper up left-hand side, around corner and along top edge of bag, ending near centre of top edge. Stitch in place.

Baste other side of zipper to left-hand side on other half of bag in same manner (edges of zipper must match when bag is folded). Stitch. Repeat with second separating zipper on right-hand side of bag.

10. Changing pad: Fold flannelette so short ends meet and right sides are together. Sew together at one short end and long edge, leaving open at one end. Turn right side out. Press. Insert quilt batting flat inside flannelette bag. Turn under 1.3 cm along open end; slipstitch opening closed. Machine-quilt 4 evenly spaced lines of stitching down length of pad.

Place changing pad inside diaper bag and close zippers.
