I use BUMERANG hangers from IKEA they cost 99 cents each they are wonderful and are strong enough to hold up an 8 yard 16 oz. kilt. Here is the webpage with them.

This is how they work, there is felt on the inside of each piece of wood which helps tp protect the fabric, the way I see it I spend quite a bit on a good quality kilt, and I want to hang as nicely as possible.
