Jury is still out on this one. The plastic is sewn to the green liner however there are spots where they missed and there is a hole. We have a 4×8 raised bed and the spikes line up with the wood of the box. So hubby cut them off and attached them to the wood. There is now a gap between the bottom of the plastic and the top of the wood. The kit doesnt come with the brackets that could have held the posts to the side of the wood. Im fortunate that my hubby is handy.
