Thanks, everyone! Lots of great ideas.
No, madpatter, I picked all those colours.
I went to spray baste it today, got the backing on and then got the top all ready to go and realized I didn't have enough spray! Frustrating. I was sure I had a whole new can in my sewing room. So, that will have to wait until I get to the shop.
Really appreciate all the suggestions everyone has come up with. Lots of food for thought.
