I keep the seams pretty simple - I stitch the pieces right sides together with a 1cm seam. Then fold the seam allowance to one side and topstitch from the right side a few mm from the seam to hold the seam allowance in place. This gives a nice appearance and extra strength.
16cm method - bag on left
Cut the fabric into 16cm wide pieces with pinking shears (length varied) and assemble in coordinating colours. Then stitch them end to end into one long strip 16cm wide. Then cut this strip into pieces about 98cm long. Stitch three 98cm strips side by side to make one piece of 'patchwork' approx. 46cm x 98cm.
Folded in half this makes one bag (the fold is the bottom of the bag). Handles can be made in the same way with 10cm wide strips or just with whole pieces of fabric.
46cm method - bag on right
If you have slightly larger pieces of fabric cut it into pieces where one side is 46cm long and other variable lengths. Then sew these together along the 46cm edge until they reach approx. 98cm and continue as before.
Enjoy!
