Skill level: Advanced Beginner It's a proven fact that young babies can distinguish black and white better than any other colors, why not make them a blanket they can really appreciate. This sensory tummy time mat/blanket is great to use on the floor yet is stylish enough for those posh nurseries that defy the pink and blue stereotypes. The spiral pattern gives it visual interest for the baby who will be crawling all over it, plus the fact that it is black and white means stains from messy baby will be easily masked. I include a picture tutorial oh how to create the spiral effect and a link to a video tutorial so you don't have to rely on just the written pattern. The blanket measures approx. 34" x34" so it is perfect for baby to toddler. If you prefer the typical pink or blue for baby, the colors can easily be substituted to make this gender specific.
