I made a great discovery today and hadn't come across it on SCS before.
I was making a card and needed to adhere vellum to the front of my card. Eyelets just wouldn't do, so I tried using my 2 way glue pen. Unfortunately, I was gluing it to Rose Romance cardstock and it was showing through like crazy. I immediately peeled it off to see if I could fix it. As I sat there scratching my head, I rembered that the glue was drying, and when dry, if you stick it onto other dry 2-way glue...it's permanent.
I thought, hey, that's cool because the glue on the card front is exactly lining up with the glue on the vellum. I stuck it back on, and voila!! You can't see the glue through the vellum. So I did the same thing on purpose with the second piece of vellum. Juse put a light line of glue around the edges, kiss it to the spot where you're going to place it and pull it immediately back off. Wait until thoroughly dry and put it back.
Here's the card. The bottom piece was accidental, the top piece was on purpose. The only problem is that you can see the glue on the upper piece a little, but that's because I was a little impatient and it wasn't really totally dry.
