I can only assume, my brain isn't functioning very well when it comes to these challenges lately. So how do you interpret the number 13??
Well this is mine and it's this week's theme on Created By Hand.
Again I googled "Lucky 13", but didn't come up with much that translated into a card, so I ended up with an ATC. I did find a nice Tarot card "Death XIII" which doesn't mean to die, but rather the end of one thing and the beginning of another. Also in the Orient, the number 13 is considered very lucky.
So I ended up creating a Bingo card and winning with the number 13, so as far as I'm concerned it's LUCKY!!
