I just (finally) finished a sweater for my mom ... it's knit using Knit Picks washable Swish.This yarn feels so nice while knitting and washes marvelously. Using a US7, I got a great "hand" with a gauge of 6.25/inch. It's a standard, drop-shoulder cardigan, but since she wanted it longer than most sweaters (it's about 3 inches longer than a normal sweater) and she likes plain ... it was quite boring to knit. Since it's a cardigan, it was just knitting back and forth, back and forth.
The hipband, knit-in button-band and neck are seed stitch and I added just a hint of color (using a skein of Swish bare) to make it a bit more fun and interesting. The sleeves are knit from the armhole down ... working in the round to avoid seams, and finishing with a k1p1 rib on US2 dpns -- I've found that ribs are heartier when you go down quite a few sizes from the body needles.
She likes it, though and in the final analysis -- that's ALL that matters!
