I don't make kits, but I group fabrics together on the shelf as I collect them for a future (unplanned) project. I have a section of shelving for "collections" of fabrics. Shelving/organizing wrapped magazine boards has been a challenge. Can't really sort by color because most is in blue family. So, I have seashell-ish fabrics section, fish-y section, striped section, 108" wide section, etc.
