Yes, she has the pattern for sale on Ravelry..HodgePodge Crochet
The pattern is a PDF, and I believe she made a tubetop to go with it as well, slightly different than the one I ended up making.
I have the pattern for the headband on HodgePodge's FB page.....but here it is below to make it easier to have....feel free to make and sell the headbands but please do not sell the pattern. Thanks!
Mermaid Baby headband accessory
Headband--pattern is for newborn to 6 months. You can make it larger by increasing your starting chain, using a multiple of 3 plus two turning chains..
DK or baby sport yarn (I used Bernat Baby Sport)
Chain 62. (gauge: the chain should be 13 inches long plus the two turn chains)
HDC in 3rd ch from hook. *ch1, sk st, hdc in next* Repeat from * to * to end of chain, ending in a hdc.
Ch 2, turn 180 degrees and work in free loop of starting chain. Hdc in first loop, ch 1, sk st. * Hdc, ch 1, sk st.* Repeat frin * to * to end, ending in hdc. (your second set of stitches should line up with the first: hdc's will be lined up with hdc's, ch spaces lined up with ch spaces, etc)
With RS together, match up ends and sl st thru both stitches to join into a circle/loop. FO and weave in ends.
DK or baby sport yarn (I used Bernat Sport Satin)

Rnd 2: *Ch 5, sc in 2nd ch, sc in next ch, hdc in next 2 ch. Sk 1 st in Rnd 1, sl st in next.* Repeat from * to * four more times (you should have 5 starfish arms now). Sk st in Rnd 1, sl to join last st.

Sc2tog next 2 sl stitches. * Repeat from * to * around four more times to complete all 5 of the starfish arms. Sl st into beginning sc to join. FO, leaving a tail for sewing and weave in ends.
