Oversized Summer Lace Coasters

During the summer, I love to drink out of those giant cups with ice inside of them. (I like my drinks coooooold!) The only problem is that they drip and sweat everywhere, and since their bases are so large, most coasters are too small for them. I made a coaster for them a while back, but my husband stole it and took it to work with him. I've made myself a new set with some leftover cotton, and I think it's a safe bet that he won't run off with these.
