This month for our Crochet Along, I am sharing my 2021 Warmth a Winter Hat Pattern. This project features a gender neutral half double crochet thermal stitch that looks great and is super cozy to wear.

This beginner friendly hat pattern is crocheted back and forth in rows before being seamed into the finished hat shape.

Warmth a Thermal Stitch Hat Crochet Pattern

My 2021 Thermal Stitch Hat is available in 5 sizes, small child (age 3-5 years), child (age 6-10 years), teen, adult (medium) and adult (large).

This hat is worked flat, back and forth in rows. The half double crochet thermal stitch pattern is made up of half double crochet stitches, worked in the back loop of 2 rows simultaneously. Once complete we seam the side edge and close up the top. This hat can either been closed up as a square hat (cat hat) or as a shaped hat, like the one in my photos.

Special Stitches

Thermal stitches are worked the same as regular stitches, except for which loops of the stitches we work beneath. You will be working under the back loop of the stitch in the current row and the remaining front loop of the stitch from the previous row, simultaneously. This creates a double thick fabric.

Work under these loops Oombawka Design Crochet Thermal Stitch

Thermal Half Double Crochet Stitch (thdc)

Yarn over your hook and insert your hook under the back loop of the next stitch and under the remaining front loop of the stitch directly beneath it, in the previous row, yarn over and pull up a loop (you have 3 loops on your hook). Yarn over and pull through the remaining 3 loops to complete the stitch.

Notes:

Multiple of 1 (plus 2 for the turning chain) (Understanding Stitch Multiples)

When I work into the foundation chain, I prefer working into the back bar (back bump) of the chain. You can work under the back loop only if you prefer.

The turning ch-2 does not count as a stitch and we do not work into it.

You may customize the height by working the repeat as many, or as few times as you wish.

You can seam the hat straight across the top to create a cat hat or ‘square hat’. I often do this for children’s hats and then add a pom-pom to each corner. Alternatively you can close the hat on the wrong side using the method demonstrated here and then flip it right-side out. You can also use the cinching method I use here (which will leave a hole at the top center because of how thick this hat is) and add a big pom pom on top.

Finishing Instructions for All Hat Sizes:

Finish off leaving a 12-18 inch tail of yarn. Fold your project with WS facing each other and whipstitch (view tutorial here) up the side edge of the hat. Once you reach the top edge you can either make this into a square hat (cat hat) or into a shaped hat. To make the square hat, whipstitch across the top of the hat, then finish off and weave in your remaining ends. 

To make a shaped hat (like the one in my photos), please watch this video example. Or use this method:

Hat Closing Tutorial

Step 1: Thread the yarn end on a yarn needle and whip stitch the center stitch on both sides of the hat together.

Step 2: Now take the hat and flatten it so the side edges are now lined up down the centre, on top of the stitch you just made. Sew through the middle stitch on both the top and bottom pieces of fabric.

Step 3: Now you should have 4 open ‘petals’ around a centre. Whip stitch the center stitch in each of the petals to the center. (Please note: some individuals find this is enough ‘closure’ for them for a slouch hat so if you like this look stop here!)

Step 4: This will create 8 ‘petals’ and your hat is now sufficiently shaped and closed.

Weave in any remaining ends securely.
