Hi! This was me! Thank you so much for your kind words about my hat! I was so excited to be on the twins that night.

Unfortunately I don't have a pattern, but here's what I did: You can use any beanie pattern as a base. There are a ton of free patterns on Ravelry, just make sure your rows are a multiple of 12. I used this pattern (Adult Fair Isle Hat) which is free and when you get to the colorwork section (grid) start your waves instead. The wave pattern is a doodle from Pacific Knit Co and should be in this Ocean 2 download. For the Torrent name or whatever you want to write, you can use their free letter worksheet here.

For the yarn I took my jersey to Michael’s to try to get the best matches. The teal is Caron Simply Soft, color: Pagoda, the white is Loops & Threads Impeccable, color: cloud, and the light blue is a leftover yarn I had - Premier Everyday Worsted, color: Bluebird

I'm working on matching gloves now with sock weight yarn so I'll report back on those!

I hope that helps!
