I did make them last year. Several sets, and yeah, they were really easy. Didn't like them tho, and found, unless I was at one friends where the mud is more like stucco (seriously, she could sell it, I think) ragging was just as good. I was also more afraid my guy would pull out the whole bags and hair with it-many times I do nothing, and his mane looks great. I have found out that if you occasionally cut the ends and even it of a little bit it grows really well. So, I cut it (*GASP*) then slightly "roughen" the ends with the scissors so it doesn't look like it was chopped off. The horses at our barn that have manes like this http://www.magoteaux.com/SWRHA/stal_...p?stal_id=1044
Never go outside, and are braided every time they are ridden. Just not realistic in my world, and IMO it is just a bit much.
