>I tried to find mylar here in Vancouver when I wanted to line a hood. It >turned out to be a fruitless search. Have those of you looking for mylar tried the local craft store? Every craft store in this area carries rolls in a wide selection of colors. You simply cut the amount you want, like buying fabric. Haven't used it for any tank purposes, but have used it in several craft projects for Sunday School. Karen Randall Aquatic Gardeners Association
