I have a problem getting things to the P.O. also. But I got mine mailed yesterday.
Great idea to send cards to MDA throughout the year. I'm thinking of sending a batch every time I have enough to fill a small flat rate box. I don't generally have "extra" cards as I can always use them for the church card ministry.
The only reason my stash has old cards in it is because I like a card so much or it was so difficult to make that I don't want to part with it. I guess sending some of those to MDA would be a less selfish way of dealing with that problem.
I've taken some time to go through galleries, but have a whole lot more to look at. I'd like to comment on every card, but if I did that, I'd be commenting until next October!
