The key is function - do you want it to just keep spray and headseas out of the cockpit? or do you want use it as part of your hide?
I use mine only when under way. It lays down flat on the deck when I'm gunning. Depending upon where I'm gunning - and the stage of the tide - I may or may not have any tall cover near me. So, I'm almost always down on my back. In a pinch, I can use it as part of my hide near tall cover if I want.

I made mine out of thinwall conduit for the bow and a piece of pine or cypress for the strut that holds it up; The upper end of the strut has a U-shaped notch to engage the bow - I leave about 2" of the hem on the dodger's upper edge (centerline) unsewn to receive the strut. The lower end is notched to engage a chock on the inside of the forward coaming. The fit of the strut is critical. It's long enough so that I have to tug up on the bow/dodger when setting the strut in place (and also when removing it), but it's snug enough so that it never has come out when under way. The lower edge of the dodger is screwed (with finishing washers) tight to the coaming so no water can get beneath if a sea overwashes the foredeck.
I use Sunbrella canvas. Any decent sewing machine will do as long as you have the right thread (a waxed nylon) and the right needle. I buy from Sailmakers Supply. The pre-wound bobbins are worth their weight in gold. (Note that Chuck is not the only gunner who sews on this site - maybe we should start a Seamsters Union....)
I fit and mark the canvas right on the boat, once I have the bow and the strut installed. I sew a 2" "hem" along the top edge to run the bow through. Once that is sewn, I install it and then mark (chalk is best) along the bottom for a snug fit.
The Tan Sunbrella Marine Fabric is a fine color for saltmarsh - but I usually wind up painting the dodger with a thinned coat of my duckboat paint - Parker Marsh Grass is what I like.
BTW: To cover the cockpit when not in use, I sew a Sunbrella cover that is draped over my pushpole (to serve as a ridgepole). It has brass grommets every 2' along its outer edges and short pieces of braided nylon line fastened to my thatch rails lash it down with slipped square knots. This approach has served well in gales and on the Ocean Parkway.
Hope this helps! (I'll have more pics later this summer when I rehab my Sneakbox - it'll be getting all new decks and needs a new dodger anyhow.)
