Washable, wonderfully soft acrylic and baby alpaca blended DK (Light Worsted) weight yarn is great for garments and accessories. It has a wonderful drape, a slight sheen, and feels lovely on your needles or hook.
NOTE: Finished "fabric", especially stockinette stitch, is looser than you think it will be. Tight crocheters and or knitters: this yarn is great for you and will likely come out close to gauge. Very loose knitters and or crocheters: definitely swatch before you go too far into a finished garment.
Cons: Unexpectedly stretchy, can be splitty (shouldn't be a problem except for beginners).
Pros: You HAVE to feel it! At this price (nearly half the price of just alpaca), and with the richness of the colors, you'll be surprised how nice it feels next to your skin. Also, machine washable is a plus.
