cindi, The wedding signature quilt that I made was a wall hanging so it has not been washed. However, I have used the pigma pens on other things and as long as you iron them to make them permanent, they should be fine. Whatever pen you end up using, read the directions so you know whether it can be made permanent and how to do that. You might even try washing some samples before using the pen on your blocks. Good luck with your quilt.

I was at a wedding 2 years ago the groom's mother is from another state and she set up the table at the reception with 5" white squares and instructions not to write within 1/2 of the edge. All the pens were there, no one stood there telling us what to do but it was announced during the meal and dance. I need to ask the bride how it turned out. I love the idea!

Press all the signed blocks with a hot, dry iron to set the ink. Then sew the blocks together.
