I've been hanging onto these leftover mosaic tiles from our bathroom just in case I could use them for something, and yep four years later and I've turned them into fridge magnets...woohoo, I don't know how I do it, lol!!?!
I used some masking tape to attach some tissue paper to card so that it would go through the printer (I got this idea from several blogs) but as you can see from my photo below my printer didn't seem to like this and chewed it up a tad. Fortunately I managed to salvage a few squares so it wasn't a total failure :) Your printer might be kinder, so you might be able to get a whole sheet??
I cut the non-smeared/chewed squares and stuck them onto the tiles using my DIY Mod Podge. When they were dry, I trimmed off the excess tissue paper and used my hot glue gun to stick a magnet on the back....yep, I'm sat on my bed in my PJs making rock magnets, awww my kinda heaven :)
I used quotes/themes from General Conference for my rock magnets but you could use scriptures, children's names, a phrase...anything!! As I was giving mine as a gift I made a little label for the top out of card, I kept smirking at my play on words, haha!!
