WHAT YOU'LL NEED
Step 1. Cut out the following sized pieces from each of the two fabrics:
- 2x 40cm high by 38cm wide (front & back)
- 2x 40cm high by 22cm wide (sides)
- 1x 38cm long by 22cm wide (base)
- 4 x 120cm long by 5cm wide (straps)
Step 2. With right sides facing, pin the straps together and sew along both sides. Turn inside out and press along seams. Pin straps in place on the outer panels and then top stitch along both the long edges 5mm in from outer edges. Repeat with remaining strap fabric pieces to create other strap.
Step 3. With right sides facing, pin each of the outer side pieces to each of the sides of the front outer piece. Sew together with a 1.5cm seam allowance stopping the stitching 1.5cm up from the base edge. With right sides facing pin the outer back piece to the other side of the two side outer pieces. Sew together as before making the fabric into a continuous loop. Press open seams.
Step 4. Sew together, pivoting at each corner of the base. Ensure to catch the straps in the seam allowance of the base seams. Clip corners of base and turn right way out, press.
Step 5. Press under 1.5cm along the top edge of the sewn outer and inner bag pieces. Place the inner bag inside the outer bag aligning all seams and upper edges. Pin together. Top stitch around the outer top edge of the bag 5mm down from the top edge. Sew another row of top stitching 3cm down from the top edge around the whole bag, securing the straps with the rows of top stitching.
