I just went out and bought Phentex wrosted acrylic knitting yarn, and it seems awfully thick. I don’t know what type of yarn I was using for my practice pieces (threw the wrapper away, so I dont know the gauge) but I do remember that it said to use size 10 needles and the yarn is MUCH thinner.
The wrapper says:
Phentex worsted
100% acrylic
knitting worsted weight
18x24 (which is the gauge i need for my sweater), on size 8 needles
edit: I’m currently working on gauge so it actually may work. but i can’t get over how thick it is!
