I've been trying to learn calligraphy also so that I could address my Christmas cards prettier and typed labels are kind of boring to me. I think an addressed envelope is a lot more personal!
To seal the deal (no pun intended) I bought some scrap book stickers {which were also 50% off} at the local hobby store. I thought this would add a cute little personal touch!
My final bill for 75 Christmas cards:
4x6 prints (60% off on snapfish) $6.50
craft paper (50% off at Hobby Lobby) $2.50
envelopes (40% off coupon at HL) $4.00
2 - scrapbook stickers (50% off) $2.00

Total: $15.00
