I've been wanting to do a mug like this for a long time. It's pretty much the same way I make all the mugs such as the DIY Crochet Humor Mug. The only disappointment (and not a big deal) is the next episode of Game of Thrones was the episode where "Winter is here" and not "Winter is coming" anymore! haha
I've only seen the "knit faster" versions of mugs, tanks and tote bags but I am a crocheter at heart even though I love knitting too. I really wanted to same font as the show and I like that in "Crochet" the distinct "O" is in the word.
