J.P.
Stretch tiny pieces at a time. Don't use the colored web (like the green and orange kind) as it doesn't stretch as well as the white. Attach a small 1 inch clump to it and gently stretch in tiny sections as far as it will go in as many directions as it will go. Keep the large bunch in your other hand as you stretch tiny sections at a time. Don't cut the web as it looks horrible if you do that. Just pinch and pull as thin as possible, pulling from the larger chunk in your hand. Overlapping web with another web makes it look more realistic. LESS is MORE. You can do a whole house with only 1 little bag. People make the mistake of using big 'ol chunks of it and trying to stretch it, but the thicker the bunch is, the less likely it will stretch and it will stay stuck in the clump. Try to attach each piece to something solid (DON"T USE TAPE!!!). Have fun!!
