Made this for my MIL and for all my DS's teachers, paras, and bus driver. It holds 5 cards with 5 matching envelopes. I ended up making 8 "boxes" and 40 cards with matching envelopes (here's the card I made ~Mother's Day/Teacher Gifts Pretty in Pink~ by ArtLvr at Splitcoaststampers. Finished "box" size: 5¾"W x 4½"H x ½"D.
