What kind of yarn is best for crocheting? I don't crochet or knit but a friend of mine does and Mothers' Day and Nurse Week are coming up soon so I thought I'd get her something to crochet with. I'm only familiar with the Red Heart brand of acrylic worsted yarn, specifically the Super Saver, as that is what Mom bought all the time when I was growing up. I asked my friend what she uses and she said "normal" yarn. I think she uses acrylic worsted yarn as that's what the scarf she made for me is. I'd like to get her something a bit "fancier" than acrylic yarn, maybe cotton or wool or specialty yarn made from alpaca or cashmere. I've looked at yarn web sites and there are lots of gorgeous super soft yarns but it seems like most are for knitting. Any suggestions? Is crochet thread different from yarn? What kind of things would one use crochet thread for instead of yarn?
