Here is a small blanket that I made for my doll.
It's very light and airy in texture.
I used fine (fingering, category 1) crochet yarn. Specifically, I used two balls of Woolike by Loops & Threads and a size E/4 (3.5 mm) crochet hook.
This is a very beautiful stitch that involves front post and back post double crochets. This stitch can be adjusted for many other crochet patterns.
