Storage in CD cases: Before I use the stickers, I make a photocopy of them and tape it to the front of the CD case. Then, I take the label and adhere it to the spine of the CD case so I can see it at a glance on the shelf (I adhere it to white paper first so I can see it clearly).
To keep the stamps in the case, I adhere as much vinyl cling as is needed to hold all of the stamps in the set, the sticker adheres to the vinyl cling (I used to use vinyl cling on my blocks to stamp with but it wasn't as sturdy as using Tack'N'Peel).
Step 3: Trim the sticker. I've tried to adhere the sticker and trim that and the stamp at once but my alignment is not very good (it wasn't when I used wood blocks either).
Step 4: Stick on block and stamp away! I've tried adhering the stamp to the block several different ways but my favorite is to use Tack'N'Peel on the blocks. That's all I use now. That stuff is great!
I used to adhere the sticker to white paper first then stick it on the stamp but my placement was always off. I got lucky a few times but not enough to continue doing it that way. Here's an example of what that looks like:
Although the design stands out against the white, I can see it just fine against the grey foam and it's one less step and less hassle.
Here's a side view of the block with Tack'N'Peel and the stamp:
Well that's it, I hope this makes sense. I love using this UM system. It works great for me. If you're interested in it, try one stamp set and see how you like it.
