the idea is to use alternating layers of mat (the chopped up looking stuff) 
and roving (woven cloth). Did you use some kind of wood for what will be 
your core? I would go with at least 4 layers of light stuff- it is much 
easier to work around bends and corners, roving for last layer because it 
needs less grinding for smoothness.

I would also consider vacuum bagging (it's a convenient size piece for that 
process) to get the best resin/glass ratio for strength-at least, that is 
what the claim is. I know it reduces air bubbles and voids in your work.
