Instead I found Northern Chunky by S. R. Ketzer in the house and though it was bulky, I thought it could do the job. Nope, the knitting was stiff. The shrug would have been like airplane wings.
So, I looked around the house again and came up with Sandnes Mini Alpakka. This stuff is fingering weight yarn, so again not what I needed, but I tried it doubled and I was able to get gage.
And in this row I've done something screwy.
I was planning to go back to this when I finished the M4A sweater, now I'm not to sure. Instead I think I'll go and finish Denis vest for school in the fall.
