A simple cravat is nothing more than a length of material (just like a long scarf). It can be lined if you want it to be stiff.  A cummerbund is slightly more complicated & I can't find any diagrams of them but I have found a photo of one (from a company that sells them) & it shows where the seams & pleated front are situated. I recommend backing this on a stiff interlining as otherwise it will tend to curl up as the wearer bends. You can see in the photo of the blue cummerbund (scroll right down to find it) that it has an elastic back fastening, this is a good idea as otherwise they bag at the front.

Good luck, it is very easy to do¦.I promise.
