Do you know this? Your project is finished and you have scraps, not enough to make more from but to much to throw away.
Take a long strip of paper and sew your scraps on.(pic2)
Cut along the strip(pic3 and 4)<
Sew the stripe between fabric (pic5), embellish if you want and you have a new piece fabric you can work with.
After finishing my garden work after a few weeks I will take my tiny scraps, make strips and use they for potholders cushioncovers or coasters.
For all, which don´t do paper piecing I must say, use a smaller stitch lengths as usually this makes it easier to remove the paper and if you remove the paper after sewing the strip to a fabric the strip will be straight (may be some scraps are sewed on the bias).
In addition it is a lot of fun to create unique combinations of fabric.-)
Your bag is lovely
