You have a lot of choices when it comes to yarn for baby blanket patterns, but most knitters recommend a cotton/bamboo or cotton/acrylic blend. These yarns are easily washable, stain resistant, soft and cuddly, and allergen-free.
Crib blankets Generally rectangular in size and measuring around 40 inches by 60 inches, so that it fully covers a toddler in their crib (or ultimately, toddler bed), this blanket should be free of loose threads, buttons, yarns and large holes that can pose a safety risk for little ones.
Don't use an acrylic, cotton, or bamboo just because of the fiber content. Make sure the yarn is soft as well as easy-care. Fibers like mohair and alpaca might feel wonderful to your skin, but they can easily irritate a baby and aren't known for their machine washing properties.
Made in rectangles, the size ranges from 36 inches x 54 inches to 45 inches x 60 inches. Crib blankets can be bought but the benefit of crocheting them is that you can customize the size, color, and stitch style.
According to the American Academy of Pediatrics, it is recommended that nothing soft be placed in the crib with an infant under 12 months old. Crochet blankets are among these items. They are not safe for babies to sleep with overnight or even while napping in a crib or bassinet.
Crochet is also faster to create than knitting. ... You'll be able to knit sweaters, afghans, pillows, and lots of small easy crafts. Because there is only one live stitch in crochet, there are more opportunities to create interesting multidirectional projects such as granny squares, amigurumi, or yarn bombing.
For a full-size blanket, you will need quite a bit of yarn, probably around 13-18 balls or skeins of yarn. Usually, afghans are very colorful, so you may have one skein of each and, if it's it's really colorful, that can add up. If the blanket only has one or a few colors, it may only be 10 skeins.
