welcome! if you're starting out red heart and caron simply soft acrylic yarns are good to learn on, and they don't feel half bad if you're wearing them either. wool is fine too, but not as cheap and sometimes itchy. my recommendation is to go with a simple worsted weight, bulky yarns and novelties can be frustrating if you're just starting out.
I am currently making the Dayflower scarf right now with Red Heart and although I am loving how it is turning out right now, it is a little rough and itchy. So next time I go to Joanns or Michaels (soon) I'll probably check out the Caron Simply Soft. Thank you so much for your help.
