I have 8.5 unlimited and there should have been an "nCloth" shelf between the "hair" and "custom" shelves. If you don't have one, then you're going to have to do as Joopson said and create one. Goto Windows>Settings/Preferences>Shelf Editor. Click on Shelves tab. If you don't see an "nCloth" in the list, create one.
Then, just add whatever nCloth tools you want to your new shelf.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
Exceed Expectations!
