Free pattern: Frond



Frond is a simple knitted cellphone cosy that can be adjusted for size or gussied up with fancier yarn and maybe even some duplicate stitch or embroidery. It uses stockinette and seed stitch worked flat and seamed.

You will need:

Medium/worsted/#4 weight  yarn, approx 30g/50m (a little over 1oz/54yds)

1 button approx ¾ – 1 inch diameter, preferably with large holes for sewing

5mm/US#8 needles

Gauge is not critical. My gauge was 4 sts to 1” in stockinette. Finished size at this gauge is 3.75” x 6”.


CO – cast on

K/P – knit/purl

BO – bind off

K2tog – knit 2 together

P2tog – purl 2 together

St – stitch

St st – stockinette (stocking) stitch

RS/WS – right side, wrong side

Foll – following

Patt – pattern

Rep – repeat

Can easily be made bigger or smaller by varying the number cast on by multiples of 2, and working fewer or more rows of stockinette.

How to:

CO 17. Any method will do. I prefer long tail cast on for a neat edge. 

Work stockinette (knit 1 row, purl 1 row) until work measures 12” ending with a WS row.

Next row: K1, *P1, K1, rep from * to end of row.

Rep this row (seed st) until seed st section is 3” long, ending on a WS row.

Next row: work seed st for 7 sts, BO 3 sts, work to end, maintaining seed st patt (ie knitting the purls, purling the knits)

Next row: seed st to gap, backwards loop CO 3 sts firmly and closely, work to end.

Next row: work first 7 sts, K the 3 CO sts through the back loop, twisting them, work to end.

Next row: seed st across.

Next row: K1, K2tog, work to last 3 sts (maintaining seed st patt), P2tog, K1

Next row: K1, P2tog, work to last 3 sts, K2tog, K1


Fold st st part of cosy in half. Seam sides from RS using mattress st, taking half a stitch into seam from each side, starting at open end and working towards fold.

Weave in ends. Sew on button.
