I don't use pins when sewing the binding to the quilt. I do use Wonder Clips for folding over and holding the binding for hand sewing.
My preference in pins is flower head pins. I had some Dritz and some Collins but wanted finer pins. Clover had some fine pins but they were sold on cards of 20 and were expensive, IMO. I ended up buying IBC pins because they had the finest shaft I could find (other than the expensive Clovers which I think were the same). They were pretty comparable pricewise to other brands. I bought them at my LQS but they're also sold at Clotilde.com
