If you love the look of the worsted weight Tidepool Beanie but wished for a lighter weight version that you can wear in warmer weather, then this one’s for you! The same wavy rib pattern hat, but scaled for fingering weight yarn.

Sizing

The hat should fit adults with a 22”-24” head circumference. Finished hats measure 10” wide when laid flat, and are meant to fit with at least 2” of negative ease. The finished hats are 11” long and intended to be worn with a 2”-3” cuff.

Length is determined by the foundation chain and row gauge determines the width.

For reference I am in the photo wearing the beanie, and my head circumference is (to my best attempts at measuring it) 23”.

Pattern Overview

• This pattern is written in US crochet terms and uses standard CYC abbrevations.
• Gauge – (20 rows in pattern = 4”) and (28 stitches = 4”) for fingering weight yarn with a suggested 3.5 mm crochet hook
• Stitches used – ch, sc, hdc, dc, yarn over slip stitch, working in back loops only. This pattern does not include tutorials for basic stitches (ch, sc, hdc, dc) or working into back loops but includes instructions for yarn over slip stitch.
• Construction – The hat is worked in a single piece, with the rows running vertically (so it grows width-wise as it works up). The crown is shaped using short rows.
• Finishing – The fabric is joined into a tube with with a seam of single crochet. There is an additional ~2” of hand sewing (mattress stitch suggested) to close the hole at the top. With the suggested construction, you will need to weave in 4 ends.

Yarn

Solid, tonal, and variegated yarns all look great in this pattern, though the wavy design will be most highlighted with a solid color. The effect is reminiscent of faux cable brioche knitting. This uses under 100 g of yarn, so it’s great for stash busting!

You can use yarnsub.com to find a yarn that will work up similarly.

• 3.5 mm crochet hook. I crochet relatively tightly so you may want to try a 3.0 mm if you generally work with a loose tension.
• Yardage – approximately 350-380
• The samples were made with under 1 skein each of Malabrigo Ultimate Sock, which is a 4-ply yarn made of 75% superwash merino wool, 25% nylon. It runs 420 yds / 100 g and usually retails around $20.00 for one 100 g
• The rainbow hat in the modeled and completed photos is in the “Arco Iris” colorway, and the yarn of the teal hat in the step by step photos is in the “Teal Feather” colorway.
