Yep, I really do love these Crate slide frames in the Navy Pier add-on. Love that there are so many in a pack, although now I'm wishing I had a second pack (which is rare for me!).
I used some of the transparency items in a couple of the frames - the Crate slides from the main scrapbook kit, the BG slide alphas from Cumberland Gap, and the Crate plastic alpha from Navy Pier. Such fun products!
