This was an exercise in improv EPP. I gave every Modern PatCHquilt member the instructions to use min. 3 lines and 2 circle segments in their individual block design. Then everybody had to use min. one shade out of each rainbow color group. Every member pieced their block by hand. Afterwards we as a group filled the gaps to connect the blocks. Rita S volunteered to put together the final pieces and Christine S to quilt it into one happy quilt.
