As with all baby sacks or “sleep” sacks, you shouldn’t leave baby alone in them.
They are cute and cuddley but baby shouldn’t be left in one until he is much stronger than new born.

I used a bit more than one skein Caron simply soft paints for my sack; Our Heritage. It’s very soft to touch but sometimes can split.
