I adore using these little magnets in my scrapbooking. They are tiny, practically paper thin, and hide very well under a slip of paper. Each one is labelled with a + or -, to help you with making a match. Lift off that little white label to reveal a so-so adhesive. If you are unsure of its strength in your project, pop a little dot of Tombo multi or some other strong adhesive. Be sure to experiment with the strength of the connection under the various layers you might be scrapping. I have used as many as three layers between the mates, and have never had an issue yet!
What have I done"
--- closures for little flaps to hide journalling or extra pictures
--- popped them on a flower to make a "memory" game for a toddler. The flowers hide the picture! Toddler just lifts it off!
--- made a little ribbon "belt" for a card
I love making tri-fold and shaped cards. The problem is, the finished cards don't stay closed. This product, however, solves that problem by creating a magnetic closure. It's easy to incorporate into my designs, and makes people ask, "Wow, how did you do that?".
These snaps work much better than velcro on many of my paper craft projects - much tidier and adds another level of professionalism. Although small they can be a little heavy for a delicate or very small paper project so you need to bear that in mind.
I used these for a greeting card idea. I placed one under 3 layers of heavy paper and the under under 1 and the closure was still strong. And the adhesive is definitely strong enough to stay put even when you pull them apart.
