I'm in the process of making 80 cards for my Dad's 80th birthday this summer. Whew! It sounded like a good idea when I first started. To help me not need 80 "Dad" stamps, I'm relying on stickers too. This tie came from a set called #1 Dad from Jolee's Boutique.
To make it look like it's on a shirt, I just cut a slit down the front of a sheet of striped paper and folded the edges back. I intentionally placed the hand-cut pocket off center from the other stripes so it would be more noticeable.
Cute results, but little effort. With many cards to make, I need that sometimes!
