I am in love with this chunky alpaca from Cascade Yarns. It's just the right weight for a sweater -- not too heavy (the purple sweater I made is nice, but a little weighty for general wear, better for chilly winter evenings when I don't have to move around too much) or too stretchy and fluffy (the white yarn from Misti Alpaca that I tried the first time around was, once again, nice, but a little too pouffy.) This yarn is looking like a good substitution for the obscenely expensive yarn called for in the "Unisex Cashmere Knock-Around Pullover" in Weekend Knitting that I've had my eye on since last summer. It's by far the most challenging knitting pattern that I've tried, but I think I may be able to pull it off. I'll keep you posted.
