Wow! Those look so cool and easier than what I was planning. I think I might do this instead. My main colors are Royal Blue and Sunflower Yellow. I'm going to use a light patterned white as a filler in my signature quilt and muslin as the signature squares. I think I may just use the yellow and blue for the front and the muslin for the back with the info. I want them to be able to use the coasters and not have to display our wedding info when they do.
