so is the top going to be wood as well? that may complicate things slightly, but not too bad. when i was molding mine and stretching the fleece and whatnot my best friend was a hot glue gun. it holds well until youre done glassing it. i used it to hold my fleece and my bracing as well until i could glass them in. id do the back and the bottom first, then do the top, then stretch the fleece. also, i agree with sndsgood with the tape thing. id put tape al the way to the back of the seat. i didnt use enough tape on my first one and also i didnt lay anything down on the carpet. my box ended up truning out a little smaller than i originally planned and i got a spot or two on the carpet. better to be safe then sorry.
