:-) Good job on all your repurposing.
I love to hit the bag sales and stuff it full of things with cute buttons. Great way to get buttons. No bag sale? If I like the buttons on a particular item, I will buy it for just the buttons. Sometimes I can use the fabric for other things. I've bought full skirts just for the fabric; also jeans and denim items. It's fun - kind of like a treasure hunt.
