I did one using hide glue, don't worry if it gels up a bit as it cools down during application, I bound it down with thick hemp string (gaps between each turn of string about the same width as the stringf) while it was drying out for a day, then took the twine off and let it finish drying for a week, it left the marks from the twine in the rawhide, but it looked pretty nice.
The rawhide was soaked before application and was a tad slippy, but I feel that hide glue on hide is somehow sorta right. (Knox is the same type of stuff as hide glue, just a bit more refined...animal protein).
It dried out real hard and worked og with a fine rasp/file.
