well, I bought them anyway and thought I probably wouldn't use them but I'm doing a 'demo' page (a friend's friend runs a party planning service and wants to offer pre-made pages to clients) for someone and thought I might try them on there.
I guess you'd be limited to using them on other pieces that you would then adhere with an adhesive? At least that's what I'm thinking.
I had the same problem so I stapled my journaling blocks then used glue to actually attach them to the page. I do like how they came out and someone who saw the page even commented on them.
I thought they would be great on a halloween page...especially if there's a frankenstein...in fact, I may try my hand at paper piecing to make a frank.
