From NuMei.com:
Smile is a splendidly soft, DK weight yarn that is just perfect for year round knitting and crochet projects. This wonderful blend of cotton with acrylic gives it more elasticity and drape for better-wearing garments and an easier hand while knitting or crocheting.

Machine washable and available in a nice selection of colors, Smile is great for everything from baby projects to adults. Whether it is apparel, toys, amigurumi, or home decor, Smile is a must-have in your stash, and would make a nice addition to the yarns you always have on hand.
