I bought the butterflies at a antique shop several years a go. All different sizes that were made with feedsacks. I had no idea what I was going to do with them. They sat in a box for along time. I was bored looking for something to make with out buying fabric. So I used scraps to make the border. Then I decided I needed white strips to make them all go together. Bought it, then my husband said why don't you just make white blocks like one we show on this board. that is how my problem and fabric shopping spree began...18 yards of extra fabric now LOL
