My granddaughter, E, and I worked together several times over the past year sewing a bunch of strips together. We sewed 3-5 strips of one color (all yellows, all greens, all reds/pinks, etc.).
There were no rules to what we sewed together, the strips were all different lengths and widths. I was just trying to get her to sew the strips together, so I could put them in a rainbow progression.
Later I sewed the reds to the oranges to the yellows to the greens to the blues to the purples. Sometimes that progression ran two feet long, sometimes three feet long. Like I said, it didn’t matter.
I have until early October to get this done for her birthday. I still don’t really have a plan for what to do with the strips. Wish me luck!
