Favorite yarn... You mean I need to pick just ONE??!? That will be tough to do. I have many yarns in my stash that I dearly love. Many I have not yet crochet or knit with yet so I can't give an opinion on how much I love (or maybe didn't love) working with the yarn. So I narrowed it down to something that I loved in the skein, something I loved knitting with, and something that feels wonderful now that it is all done!
One yarn that I bought a while back and finally found something to make with is this:
It is Plymouth Yarn Baby Alpaca DK Paint and it is such a soft lovely yarn! I bought it at Webs last summer. I made it into a pair of socks that I can wear around the house. They might be OK in a pair of runners (haven't tried that yet) but I doubt they would fit comfortably into other shoes. It was a dream to knit with and feels so incredibly soft! Here are the socks that this yarn became:
Least favorite yarn... This would have to be the yarns that fall into the "fun fur" category! It's not a single yarn but a category of yarn... I once bought a BUNCH on a Black Friday sale for something like 50 cents a skein and then I couldn't figure out what to do with it... I actually went back to AC Moore to buy more while it was still on sale... Here is what some of that batch looked like (a nice fuzzy variety):
I wasn't knitting much at that time (still a pre-beginner) so crochet was my option. Unfortunately I found this stuff impossible to work with... Finally after researching what others had done with this, I tried using a second strand of yarn along with it and made myself a giant fuzzy afghan (after of course going out and buying even more of the stuff because now I needed to have enough to finish the afghan!). The afghan is actually nice, warm, and fuzzy AND fits a double size bed. Perhaps not the most pleasant crafting experience making the thing, but the end result is not too horrible (well, that is open to debate, but I kind of like it although I would NEVER make another one!)
One day I may learn (maybe, but don't hold your breath) that I do not need to buy all the yarn I can get my hands on just because it is on a good sale!
