Iced Gems. Loved these when I was a kid! I used to bite off the icing & put the cookie part back in the jar. Needless to say, when my mom/grandmother took the jar out to serve to guests they were not to happy to find a jar full of un-iced cookies.
What I Used: clear flat marbles (You can get these at any craft store, and they are about $2 for 18 or so) scrapbook paper E6000 clear craft glue (You could also just use modge podge) 3/4″ magnets hot glue
