I had planned to put two on each side, but guess what?
I ran out of the background fabric again! It happens all the time and it just forces me to become creative. I found this purple fabric I just bought on my fabric spree last week.
I decided just to add 6" of that fabric. It's the part that will be the beginning of the fabric that hangs down the side of the bed. I wasn't really happy with it. Finally the idea occurred to me to make three of the corner blocks with the same background. I am more pleased now because I think it looks more like I had planned it to be that color.
You may have noticed that I have not sewn all of this on yet. I need to lay it all out on the bed first to make certain that the purple falls down the side as I am planning. If it does not, I am in big trouble! That, by the way, is one of the big pluses of making your own quilt. You can really custom fit the pattern to your bed. Personally I like a few extra inches up toward my neck so I can pull the quilt way up to my nose. I always make my quilts with plenty of extra fabric at the top.
