I'm not sure how much you need, but there may be some books near the yarn where you can get an idea of how much yarn they use for baby blankets. And what size hook.
Sounds like a plan I think I've felt the bernat kind before my mom make a baby doll blanket once and it still super soft after 10 years lol I hope it's the same kind @tattie
i just finished a baby blanket with ored heart but felt it was a little heavy lol so im starting one with bernat i liked this one better so much softer in my opinion @ak16 just walk around and feel all of them pick ur favorite (:
