ISO ColourMart yarns?

I really want to try out some ColourMart yarns but as someone who's still pretty new to knitting and has only worked with the budget-friendly stuff available at Joanns/Michaels, I'm not sure what kind of yarn weight/fibre I can handle and therefore can't decide what to buy/sample from their website. I thought it might be better to try my luck here first and see what everyone else likes to get/has leftover from their projects! I mostly make sweaters and tops, am curious about cashmeres, wools, cottons, and mohair! Does not have to be sweater-amounts, but would probably be more interested in larger lots!
