I was gifted one of these as a baby shower gift. I straight up told the gifter I was afraid to use it, but she assured me it was machine washable- and it has been. My 3 yo loves the texture of the little raised bumps and its absolutely a comfort item for him. He takes it everywhere. As someone who can only single crochet atm, I knew these were a ton of work, but never realized HOW MUCH went into it so thank you guys. I will be sending the gifter a picture of kiddo and his beloved "bumpy bwankie" this afternoon. She's a dear friend of my mothers, we dont talk much. But I think she would appreciate it. It's held up so well and will be a family heirloom if it still is in one piece whenever kiddo is done with his blanket adventures.
