Knitting Pattern for Sand Dollar Hats: A Unique and Charming Project for Babies and Adults

Sand Dollar

My unofficial job title ought to be “fairy godmother in training." After all, my day job deals with children, I live within spitting distance of the ocean, I play with desserts and yarn in my "spare" time, my car (and possibly my house) has been described as “bigger on the inside," and above all I love a good story. Sand Dollar is, naturally, the product of such...auspicious beginnings? With the weddings of two of my best friends a year and a half ago, it was only a matter of time before the baby announcements started to roll in. So with not one but two bundles of joy on the way, what's a fairy godmother to do but drive out to the shore and start gathering ideas? But then it was winter and the waves were sad and the sky dreary and the clam and conch shells fragmented and lonely, and I had my mind on hats. Maybe my ears were cold. And then eureka! The vision of a sand dollar started to form in my mind: round, creamy, and promising good things and warm hats. Baby Sand Dollar was conceived as a cross between a tam and a newsie cap. It's knitted from the top down and can be increased or decreased by a factor of 30 sts depending on gauge (which needless to say is not important here) or size of baby's head in question. You could knit it for a boy or a girl depending on the yarn you use. Pair with a knitted cardigan, e.g. Haiku, and we're talking serious cuteness. But why let the babies have all the fun? Knit this baby up in a more blingy yarn or get happy with beads, and you can have your own fairy hat. Since the pattern is essentially modular, based on yo increases over the sand dollar “arms," you can size it up as much as you like for more of a slouchy look, and you can stiffen the double-knit peak with interfacing or plastic to balance out the extra width. So go ahead, break out the wands and the fairy dust, and don't be afraid to play.

SIZE

Baby and Adult, can be modified to suit size of baby/adult.

FINISHED MEASUREMENTS

Baby version: 6.5 inches widest diameter, 4 inch opening diameter, brim 3.5 inches at widest point by 1.5 inches in length. Adult version: 10 inches widest diameter, 6.5 inch opening diameter, brim 6.5 inches at widest point by 2.5 inches length.

MATERIALS

Baby version: Cascade Cherub DK [55% nylon/45% acrylic; 180 yd/165 m per 50g skein]/ colOr: Jade; 1 skein Adult version: Cascade Sunseeker [47% cotton/48% acrylic/5% metallic; 237 yd/217 m per 100g skein]; color: Pale Blue; 1 skein 1 set US #7-8/4.5-5 mm extra-long double-point needles (circulars work as well)

GAUGE

24 sts/24 rows = 4" in stockinette stitch for both versions Note: gauge is not important in this project.

PATTERN NOTES

Initial round might be easier if worked like an I-cord rather than immediately dividing 5 sts Ontodpns. I divided the hat into sections, i.e. “arms,” “arm tapers, "hat body increases,” “brim." Each of these sections can be modified in size individually. For example, more arm rounds and/or hat body increases to make a floppier hat, or fewer decrease rounds for a wider opening/larger head. I made my stitch counts at widest circumference and hatband divisible by 15 to please my OCD, but it's not strictly necessary. If modifying your brim: working an even number of repeats of rows 1-6 will give you the adult version of rows 7-8, while an odd number will give you the baby version. Working an even number of repeats of rows 7-8 will take you to the row 9 from the same version, while an odd number of repeats will get you the opposite version's row 9. For the row 9 repeats, once you get to somewhere between 2 and 8 sts remaining, if it looks like a smooth curve, go ahead and break yarn and draw through.

This is the “back" needle.

Double-knit brim

Holding 2 needles parallel (with 1st st on front needle next to last co st)with yarn in back , k1 from front needle, bring yarn to front, sl 1 purlwise from back needle, repeat across row until all sts on same needle. 6o sts. t row (bottom-of-brim, we'll call it WS): (k1, sl 1 purlwise) to end of ror Start shaping decreases: Row 1 (RS): k2tog, (k1, sl 1 purlwise) to last 2 sts, k2tog. 58 sts.

FINISHING

Double-knit brim forms a pocket. If desired, cut a piece of interfacing or plastic (I used a milk jug) to shape of brim and insert into pocket. Sew pocket closed using tail from cast-on (use your favorite grafting stitch, as it's the only bit of grafting you need for this project). Weave in ends, block if desired, and enjoy.
