A vest is perfect for fall. We are hooked after wearing this for a few nights. It gives you a comfortable warmth over the shoulders. The vest is knitted in a wave pattern, hence the name. The yarn is a mix between Pickles Extra Fine Merino and Pickles Cashmerino Silk, the latter gived the garnment a nice fall. If you enjoy tv-knitting without thinking, we recommend that you knit normal stripes instead of wavy stripes. The knit is very stretchy, and the size is XS if you wish to close the vest.
