I'd like to offer a very special thanks to Harvey Flatbush for allowing me to host his project here. Folks like him who are DOING this and who are willing to SHARE their work with others make this an exciting undertaking.
I have a nice set of plans I made up for making garden row covers ... One thing I might add to the directions. The clips for mounting the clear plastic onto the frames should have all four corners and the straight edges rounded. Otherwise they will cut and tear the clear plastic covers.
