Is "Itty Bitty" a brand name?
I have done 5x7 albums.....but I've been using CM ones. CM does make really neat supplies for 5x7 albums, like the snap packs. The small shortcut strips work great too.
What sorts of albums are you doing? What kind of supplies do you need? There are several places I have ordered from online, and all have been good. I think there was a thread with a listing of them a while ago.
Have fun!
