Chain 5 sl together
Rnd 1 - sc in 2nd chain from hk, hdc in next, dc in next, work (2hdc in last, ch 2, sc in second ch from hk, 2hdc) in last ch. Working now on the opposite side of foundation ch. dc in next, hdc in next, sc in last.
It works fine. Make a chain of 5. Skip the first chain, single in the 2nd, half double in 3rd, double in 4th.
In the 5th and last: 2 half doubles, chain 2, skip the 1st chain again and make a single in the second. Then, in the 5th of your original chain, work 2 more half doubles.
Then, in the "wrong" side of the original chain, work a double, then a half double, then a single to match the first side. Finish off with a slip stitch.
I make mine similarly - work a row of stitches, picot in the middle of the cluster at the opposite end, work a matching row of stitches down the other side
Any good?
