Free Pattern – Tesseract

Blocks of alternating textures twist around this fun to make hat, capped off with a spiral design. Available in 6 sizes, so you can make one for the whole family. The entire hat is made in only half double crochets, for extra squishiness. Varying textures, created by working the stitches in different loops, keep it interesting and fun. Change colors as you go to create your own unique look and to use up scraps!

I designed Tesseract for the 2018 CGOA Chapter Challenge. Chapters around the country are competing to make sets of chemo hats to donate. The solid design and soft feel of this hat make it a great choice for charity projects!

Hat 

Turn work so that right side is facing.

Note: This section is worked in continuous rounds. Do not join, turn, or chain at the start of rounds. Stitches will naturally shift slightly with every round. You may find it helpful to mark the first stitch of each round.

Rnds 2-6 [8, 9, 10, 10, 11]: (Hdc in third loop of next 5 [6, 7, 8, 9, 10] sts, hdc (normally) in next 5 [6, 7, 8, 9, 10] sts) 8 times.

    I’ve gotten stuck on round 1 of the hat (size small adult). I can’t seem to fit 72 hdc stitches on the boarder and was wondering if you had any suggestions for fitting those last few stitches in. I’ve only managed to fit 66 out of the required 72 hdc stitches.
    I have 44 rows of 7 hdc each and I can’t figure out where I went wrong. Any suggestions would be much appreciated. I know it’s hard to try and fix a problem you can’t see when it comes to crochet.

      Hi Elise! 🙂 It’s purposely more stitches than would make it even..that’s what makes the ribbing section cinch in. 72 stitches is 8 * 9, so what I do is use stitch markers to divide up the edge into 8 manageable sections, then work 9 stitches in each section. Check out the tutorial on working evenly around (linked in the recommended resources section). You may find that helps.
