15.75mm hook
T-shirt yarn made from old white t-shirts, dyed with RIT dyes in Navy, Teal, and Apple Green colorways (none of whick came out as advertised :p) and some navy blue t-shirts, courtesy of my brother.

Rounds 5 and 8 (and since my rug is larger, also round 11) seemed to have far too many stitches and made the rug curl, so for those I did 2dc in each ch space and a dc in every other st, instead of the 2dc in each ch space and the dc in each st that the pattern called for.
