I am the same way. I have several embossing folders, etc. that don't get used. And it seems I have no imagination when it comes to stickles. I have some nesties on order with Amazon.com, and I really want to incorporate them into my LOs. We'll see!
I saw the Artbin magnetic case in a Paper Wishes catalog. I didn't order the carry case--just the set of 3 magnetic sheets. I will keep them in a folder. I got the shipment today, and it seems like they're going to be very handy and convenient.
