First up, you can show your love of all things Katamari while keeping your ears warm with Nikol Lohr's Katamari Prince Earmuffs. Just click the link to view the free pattern, courtesy of Shojo Beat magazine.
And of course this wouldn't be Cthulhu Crochet and Cousins without a mask of our favorite Lovecraft monster. This cthulhu mask was crocheted by flickr user djonesgirlz. No formal pattern, but djonesgirlz does give a link to the original ski mask pattern that was modified to make this awesome monstrosity and an explanation of how the tentacles were created.
Craftster user mamaedgar's son really wanted to be Yoda this Halloween so she whipped up this Yoda hat for him in just two days. I'm impressed! That's a lot of stitching in just two days. Click the link to see more photos and the free pattern that mamedgar was gracious enough to share. I really admire the detail on this one, including the bits of fluffy hair around Yoda's ears. Nevermind, Halloween, this hat would be great to wear anytime. Of course, the original pattern was designed to fit a four year old, so some alterations may be in order if you want it in an adult size.
Running short on time, or just a beginner? Here's something a little simpler that could still be part of a pretty awesome costume. Just add a sword to this traditional masquerade mask, created by Priscilla Hewitt and you could be Zorro, or deck it out with some sequins or beads for something a bit more flashy.
Sadly, these last two masks aren't available as free patterns, but I liked them so much I decided to include them anyways. I'm guessing that more experienced stitchers will be savvy enough to figure out how to make these, or at least something pretty similar. First up, start practicing that gravely Christian Bale impersonation so that you proclaim yourself Batman while wearing a crocheted cowl, like this one stitched by Etsy user nmelone13.
And last, but not least, Dr. Zoidberg courtesy of another Etsy user, blackfezstudios. I absolutely love the eyes and the colour of yarn that was chosen for this one. It makes for a very realistic Dr. Zoidberg!
