SHEL,

Making molds is fairly straight forward modeling technique that is not too 
tricky to learn. One of the simplest methods I have found in the literature 
is on the Composite Structures Technology (CST), website. It is very similar 
to the techniques I use when I make mine. Go to their website and look under 
Mold Making, where they describe building a simple female mold for a cowl. 
Extend the method to your canopy

As you get more experienced with the mold making technique, "clamshell" molds 
for making propellers, landing gear, spinners or other more complex parts, 
are also fair game. Hope this helps
