I'm sorry about the delay. I had these blocks up Monday but, I got the picture today. These are some old blocks that I got from my mom while on vacation this year. They look like sample blocks that were made to try a pattern out. I'm planning to make a quilt with them. I don't have all of them on the design wall. I've decided to make a sampler with the blocks. I need to make a decision about some of the fabrics in the blocks. A few of the fabrics have age spots and a few are very thin. I need opinions about this. Should I replace the fabrics or not?
