I cut mine 3" from the bottom. I stuck the big piece in a crevice and the little stalk grew a new head.You can't glue leathers. You need to get a rock with a skewer or something along those lines. Also if you cut the stalk a new head will most likely grow off the old stalk.
How did you get it to re attach. Or did it do so on its own just by being James in the crevice
