I have been making mine bigger due to requests...I have been making borders with left over materials from my blocks. They come out great...I agree with the mattress size is an issue...I am also thinking of trying to make a few larger since they no longer cover the mattress. I am trying not to buy any fabric this year...using only my stash so this also makes me more creative in my thinking. Its actually quite fun and using materials that I would not normally use for my project.
