1 Download the templates, then cut two printed fabric pieces for each section, adding a 5mm seam allowance and checking the shapes are the correct way round. Lay out the pieces to make two bands of fabric and sew right sides together. Press the seams and topstitch 2mm away from them in a contrasting thread.

2 Cut vegan leather using the template and sew the fabric bands to each long side. Lay the panel face up on the quilt wadding, then pin in place on the fabric section only. Topstitch again, 2mm in from the first set of stitches. Trim the wadding to the edges of the panel, and zig zag stitch. Cut the lining to the same shape and size as the bag’s outer panel.

3 Cut two patterned fabric pieces, 3cm x 8cm, then fold in 5mm on each short end and glue. Fold the strips in half and wrap them around the ends of the zip. Topstitch close to the folded ends to create tabs.

4 Place the outer piece right side up, lay one edge of the zip against a short side and add the lining face down on top. Sew along the top seam close to the zip. Pin and stitch the other short ends of the outer and lining to the other edge of the zip in the same way. You should now have two right sides together with folded panels on either side of the zip.

5 Open the zip and match up the sides of the bag’s outer, then sew down each seam, catching the zip tabs as you do so. Trim the excess tabs. Squash and fold the bottom corners of the bag, then sew across the points, 3cm from the tips to make a box bottom. Match up and sew the lining in the same way, leaving a 10cm gap in the centre of one for turning.
