I actually hand sewed mine for Kaitlyn . I cant remember the size of material ..I think about 1mtr deep and 1.5mtrs long ..but then that was when she was about 4months old I think.

I also made little slots in the top of mine so I could tuck Kaitlyns hands in as she often got our and woke herself. She really loved being so securely wrapped...but it looked a little like a straight jacket hehe.

Happy Sewing!
