We bought our bimini from the canvas shop on the site chandlery. It provides excellent shade for sun from the sides and aft, and is not much help for sun over the bow. But in that case, the sails do provide some cover. This picture shows the addition of a custom canvas awning that zips onto our bimini to cover the cabin and rest of the cockpit at anchor/in port. We also got this from the site canvas shop.The advantage of this arrangement is that we can leave the boom-end sheeting on the traveler behind the rudder post. Boom end sheeting is the best approach for controlling the main, and minimizes the resulting stress on the boom itself.

See Awning with the flap down

This shows the awning with the flap down. Rigging the awning takes less than 5 minutes to zip it to the bimini, then rig the corners and flaps with shock cords. Their are two slots in the aft end of the awning to allow the mainsheet to pass through with the traveler either far left, or far right. In the rain, we rig shock cords from the main halyard to the forward end of both slots, and lift them up. This prevents unpleasant draining into the cockpit from the awning.
