I've been making baby blankets for almost four years (including one for my nephew Kai, who is sporting his blue blanket as he hits the backyard for some playtime!) The acrylic-based yarn I use stands the test of time, and is machine-washable/dryable. The blankets I've made have measured about 12 square feet (about 3-4 feet per side). I've used a variety of colors, all of which are included in the sampler, but please ask if you're looking for a specific color or a blend! The blankets come out "light and airy looking" (this isn't a tight knit) so the blankets are good for all kinds of temperatures!
