Having made my first flimsy I realized that If I washed it I could perhaps square it up more before proceeding. Well it was red and cream and Wow I had a lot of bleeding. The worst offender was one of my most expensive fabrics. So just yesterday I was setting up to work on another quilt and I found a green version of one of my bleeders so I threw it in the sink but it did not bleed.
This quilt (just referred to) was put away last year as I ran out of fabric in the right colour. I have just realized that my block may not work, I don't have a pattern. I have seam allowances for 2 internal seams but not the other two. So I have just decided to make a sample block and Tartan I think you have a terrific idea about your test blocks. Thank you.
