I gave up on that super bulky extra fuzzy yarn for now. The stuff it just so fuzzy it's hard for me to see what I am doing and tough to work with and I'm not experienced enough for that yet.
I have started another scarf but instead of a straight garter stitch I am trying doing 2x2 ribbing for it. The K2,P2,K2,P2... is forcing me to slow down, count stitches, and make sure I'm not adding any extra stitches in the rows. So far so good.
I might eventually actually finish one.
