I had ordered these and then was afraid they would be difficult to use but it is soooooooo easy to thread through the holes of my homemade Smash books. I read a tip of what to do with the ends - I used hot glue to attach a bead and they stopped unwinding -- plus adds some whimsy to them. I'm ordering more!
I know these are fairly new, love how easy it is to thread through your Cinch project. Not sure what to do with the ends. I just let mine "as is". It is great to have all these colors at your disposal, and it is a really cute look to your albums!
