I can't remember where I found this stitch and I don't have the link open anywhere. It is 3 rows of chains followed by a row of 3 double crochet in each chain. It reminds me a bit of a lattice.


To start I cast on in a multiple of 4 + 5. The first row was chain 5 and sc in every 4th stitch. The second row is chain 5 and sc in the chain space. The third row is chain 3 in and sc in the chain space. The fourth row is 3 dc in the chain space - repeat.
