A friend of mine brought over this fabric that she is making a bed cover out of. She wants me to quilt it, and I started by quilting straight lines down and across to separate the blocks on this pattern. But there is approx. 12 " blocks in the design, and I need to figure out what to put in the middle of each. Any suggestions? Has to be something simple - I am doing the fmq with a Sapphire 850. She has had this fabric for about 8 years, started several years ago, and now has brought it to me to do some quilting on it.
