Sorry if this has been answered before. I have checked the forum and printed off alot of material to read and I think I do understand how to quilt as you go with the sashing and I have watched the fun and done method and I understand that. But here is the stupid question can you use any quilt block you want to, or do you have to use specific ones? I need to learn this method until my brother remodels my one car garage into a craft room for me, cause I am getting very frustrated finding a large enough area to put my quilt sandwich together at.
