Attached is a picture of a Wedding signature quilt that I made for my niece. I had the blocks all made, and used large squares of the yellow for practice for everyone. Some drew pictures, some wrote poems. I put the large squares on the back of the quilt. She sometimes hangs it with the back showing. LOL
They had a meet and greet in the church basement right after the ceremony, and that is when I had everyone (Kids included) sign the squares. I put freezer paper on the back of the fabric.
