I designed this for a friend’s new baby. It’s a baby snuggle sack, meant for keeping your baby warm while you snuggle them. You shouldn’t let a baby sleep in it.
The pattern is laid out round by round, rather than in chart form and it’s constructed seamlessly from the bottom up, for a very quick knit. I included a link to Cat Bordhi’s youtube video of how to do Judy’s Magic Cast-on, which is what I used to start this piece.
