I've had some fun making magnets or necklaces using Diamond Glaze and scrapbook paper (or photos)--so why not combine the two? A co-worker had some earrings that had the same premise (although fancier than a bottle cap) that I used as inspiration. Now I can switch out my necklace depending on my mood or outfit :)
Bottlecap necklace blank (Hobby Lobby)
Patterned paper or photo
This was a super fast, super easy project (and very inexpensive--the magnets were 1.99 for 6, but I had a 40% off coupon and the bottlecap necklace was on sale for 4/$1). I looked at some other necklace blanks that were flat, but I was concerned that the magnet could get knocked off.
First, find the scrapbook paper that you like and roughly cut out a circle a bit larger than the magnet. Flip the piece of scrapbook paper upside down and spread a thin layer of the Diamond Glaze (you could use any glue here, but to keep things simple, I just use the glaze). Press the magnet into the glue. Let it set for about a minute, then use scissors to trim around the edges.
Make sure you don't have any excess glue dripping down and flip the magnet over so that the paper side is now up. Puddle some Diamond Glaze on top of the patterned paper and smooth out (I use a bit of cardstock, or in this case packaging from the bottle caps) as a spreader. Go slow and make sure that you don't have any air bubbles. Careful, if you are doing more than one pendant at a time, keep them apart--if two magnets with wet Diamond Glaze get close together...not so good (not that I learned that the hard way or anything). Let dry for a couple hours (or overnight).
Thread a chain through the bottlecap and decide which magnet to pop in! That's it :) Try it out for different holidays (or make an advent necklace!) or to switch up between favorite sports teams or your school mascot.
