The holes arnt big enough to get stuck on, you cant even see any really cuz I made it tighter than normal. I had the boys test one before I made them. Oh man! They love them, everyday I see them sleeping in them, hehe. Yeah, Ill look around on the net for patterns. I have never tried knitting before...I heard its hard. I was thinking about sewing hammocks but I dont know how to use the machine. >.<
