This bag was made with Daughter 3, who will be 10 soon. She chose the fabrics, the order of the strips, and did some of the sewing.
She found it difficult to cut with the rotary cutter, her hand was moving too much on the ruler. And sewing along the edge very precisely was also a challenge: I had to help a bit at the end.
Now that the bag is finished she is very happy with it, took it to school this morning. And she told me one of the pockets was perfect for her water bottle.
I love doing things with my girls, and hope they will catch the sewing bug... there are worse addictions.
To make the pockets i sewed a tube of fabric on the width of the lining with a horizontal line, where the flat part of the bag was to start; and added some vertical lines of sewing to separate 3 pockets. The sides are in the seam of the lining.
