Someone not on this forum suggested that I use my round glass dining room table as a pattern for a small lap robe or for a baby.
I could tape white newspaper to fit it, mark out 4 equal pieces and keep on marking till I have enough to use up all my fabric of whatever colors I want to use. Then cut them out, and add seam allowances for each one when cutting fabric. It's about 43 inches wide, give or take an inch or so.
Just might do that. Then probably would have to put a round center in it to disguise the mismatched points in the middle of the whole thing.
I got a large roll of unprinted newspaper from the newspaper office right after the AM run was over and the office opened. Cost about 4 dollars and will probably last me for years.
