I have tried and failed in the past to find anyone retailing eVent fabric. I think the only hope is to contact some small manufacturers (Mountain Laurel Designs being the most likely) and see if they will sell you some. Screen is easy - the lightest is Nanoseeum from thru-hiker.com at .7 oz/yd. and they also have spinnaker fabric, which may be an answer to your other post re the hammock fly.
