Enchanted Fabric is a material in Thaumcraft 3 used in early Thaumcraft armor and clothing recipes.
It also is a researching tool, used for Research, for a combo of aspects.
"By combining spider silk and wool and infusing them with raw vis, you have created a silky length of magical cloth that has numerous uses. You're not quite sure what those uses are yet, but you are sure you will think of something."
Enchanted Fabric is crafted at an Arcane Worktable using four string and one wool, with a cost of 5 vis.
