Sometimes a yarn decides it wants to be something else than what you originally intended.
Patti from Sweet Grass Wool sent me some skeins of her luscious Targhee to play with. I had a fingerless mitten pattern in mind, with sinuous cables curving back & forth (never crossing, so not sure if I should call them cables precisely, but regardless), a little asymmetric, dividing the mitt into moss, garter & stockinette stitch sections. I thought it sounded nifty, and the charts definitely looked neat. I decided to try her single ply hand dyed skein. I did a little swatch of a cable and some moss stitch (really just to verify needle size) and it was scrumptious. 
I cast on. The yarn loved the broken rib ribbing. However, when I got to the main pattern, the yarn said no. It liked the moss stitch (a lot), and it liked a little bit of the waviness, but the rest? Nope. Not one bit. It wanted to be simpler, more…manly. Which is actually fine — there aren’t that many manly mitt options.
I’ll be looking for a couple testers in the Ravelry FPT group in the next few days — if you’d like to be a test knitter, watch for the post.
