Here's a quick way to tell someone they mean the world to you.
Take those little jars of glitter you can get at the dollarstore with the cork tops. Dump out all the glitter (or leave a tiny bit in the bottom if you like)
Take one of these.... head pins? Eye pins? I can't remember what they are called. Anyway, shorten it using pliers or wire cutters or scissors.
Cover the stem in glue (jewellry glue would work best, but hot glue works as well)
Then shove it into the cork (make a hole first if you have to)... and scrap off the extra glue
Attach necklaces or key chains.
Write meaningful notes on slips of paper....slide them into the jars rolled up tiny... and add any other mementos you feel like
And there you go! A little portable thank-you or word of encouragement!
