I've never made anything nearly as fancy as what MH made, but I did make a very simple keepsake when I cut Caleb's bridle path. Maybe one like this will do until you learn to make something fancier?
I tied the hair in an elastic band then cut it. When I got home I removed the band and dipped the end one inch deep into yellow wood glue. Then I tied a slip knot made of white dental floss and wrapped it around very tightly going up and down the gluey hair. When there was a good tight wrapping I tucked the end securely. I then dipped the entire thing in the wood glue then left it to dry for a few weeks.
I use it as my medicine charm on my dreamcatcher instead of the owl feather that was there: Picture 790.jpg
