What's Your Lucky #? +DIY+

I did a last minute DIY project today with these numbered mosaic tiles I picked up a couple weeks ago. I simply used E6000 glue to attach the numbers together. Then I glued the tiles to a pair of earrings that I didn't wear! They're bold, fun, easy to make and definitely a conversation starter.

13 and 7 are my lucky numbers. What are yours?
P.S. Remember when "#" was called the pound sign or symbolized "number". Where did HASHTAG come from??!?!?!
P.P.S. I wikipedia-ed that and found out that "#" has always meant HASH in COMMONWEALTH ENGLISH, not American English. Hmmm... was I supposed to know that already? Haha
