Which holds heat better, x1 bulky or x2 worsted? (large gauge crochet/knitting) I know weight may differ, but ultimately the area #5 Bulky takes up is comparable to x2 strands of #4 Worsted. Though there's more possibility of spread out spaces throughout the project. I'm not sure how much it really matters.


So... Which is "warmer" - x1 strand of bulky cotton or x2 strands of worsted cotton?
