I use the red ones all the time. They are perfect for binding and very handy to hold small stacks of cut pieces together. I even write myself notes and attach the notes to my blocks with the clips. I also make doll clothes and sometimes I don't like to pin satins and fragile fabrics because I don't want to make pin holes. The clips are perfect! I use the little clips for a variety of little chores. I bought mine from Ebay for $1.79 per 20 pack (free shipping)and they compare very favorably to the ones that clover sells. I bought one pack and liked them so well I ordered 2 more packs. I also bought the larger size and use it a lot less.
