i got out one of my MANY stamps i have hoarded from my Cocoa Daisy stamp subscription, some spray ink (mr. huey) and a date stamp i recently picked up on clearance at target (american crafts)
to protect from over inking that may be on the numbers, just put a piece of masking tape on the date itself, ink, and remove to stamp. all stray ink is hopefully on your masking tape. and you can use the same piece of tape a few times. i like the sentiments on a date stamp as much if not more than the date portion itself.
i also used a couple stickers from my new stash of heidi swapp i picked up at michael's this week. i FINALLY found her color shine mists at the michael's in coralville. AND got "buy one get one 1/2 off to boot"!
