Here are the orange slippers I made for my son. I used Patons Classic Wool Roving Bulky which I substituted for holding two strands of worsted wool...much nicer to work with. Very soft. About 4 sts/in.
The cowl is made with Malabrigo Rasta Pure Merino Wool, super bulky in Ravelry Red...2 - 2.5 sts/in. I apologize for the blurry photos, but the red is so vibrant, it is hard to photograph.
