What to watch for.......do you want it soft and subtle or do you want it preserved..........
Snaketan does the first quite well. It will be soft and what you'd use for say a purse or handbag or for a NICE headban.
The other....such as borax and salt or drytan. Great for stretching hides on the wall for display, but not for making clothing etc. Can work for headbands, but definately a different "look" than the snaketan.
There are other homeade remedies on the net. One popular one is using antifreeze.
