I bought Patons Stretch Sock yarn and started on Porphyria fingerless gloves. And in consideration of the extra large size of my hands I've increased the number of stitches by about 20% - which works out to 2 extra pattern panels. And so far so good.
I know I promised never to buy variegated yarn again - at least not without seeing a swatch. But I did, and so far I'm not regretting it. As it knits up it looks a lot like fudge ripple ice cream. Pretty yummy!
