I knew this Spooky Bingo Bits stamp set #123946 (clear) looked like a fun one when I saw it!  And then I got the idea from a long time ago to use those clear "rocks" to make magnets with the stamp set.  I need to search deeper in all my craft stuff to see if I have more pebbles (I think they are called) because these would be so fun to make!

I stamped on Whisper White and punched out with the 1" circle punch. In the past I glued the pebble on over the stamped image and then cut around the pebble shape with a scissors when dry.  Just depends on whether or not you want it to match the pebble shape exactly.  I used Crystal Effects.  Just glue on a magnet to the back and you're done! These are so easy and fun!
