I first read about LTC's sometime in late 2011 but it wasn't until I saw the Blog Post by Ryan that I wanted to make my own. My first card was something I quickly made using my signature stamp at that time.
Name: Mountain Biking Around "The World"
Swap: Marjorie's Potpourri (February 2012)
Limited: Yes, 24
The card is a printed background of Expedition Everest at Disney's Animal Kingdom. I used my mountain bike signature stamp from 2011.
I had planned on creating a card for each of the four parks, but that hasn't happened (yet!)
