I want to do a postage stamp quilt too. I started out making four patches from leftover squares and I'm undecided whether to incorporate them into the postage stamp quilt because they are each made of two fabrics. I think it might be nice to scatter them throughout.
In thinking about strip piecing, I was wondering if it would work to do a swap with strip piecing. For example, I take 25 (or so) different fabrics in my stash, cut a 1 1/2" strip from each and sew the strips together. I then subcut this into 25 (or so) 1 1/2" strips. Each of these strips would have one each of the twenty five fabrics. I swap 24 of them with other swappers, so everyone ends up with 25 different strips.
Would that work? Would anyone be interested?
