Thanks Ingrid, Suzeeq.
Oops, maybe I didn't make myself clear....I am asking about the texture in the white blanket behind the baby hat.
I found an interesting pattern to test, it's this:
k1, *yfwd, k2tog. repeat from * to last stitch, k1. Repeat this row.
Would this pattern make a nice, loopy, soft blanket? going to try it today.
