Hi again.
Sometimes when I'm cleaning/curing/tanning several -sometimes many- skins,
I've noticed that bird skins can be de-haired with no aparent different results at all. (you don't get more feathers or something)
Also, this can be applied, -in the same skin- several times at different stages of treatment, after cleaning, after curing...
I found this particularly because of the mess to remember in which state each skin was at the moment,
and at one point I realized I did de-hair the same bird skin a couple of times, so far that skin was in treatment like close to a week in all.
Maybe adding a red sign 'This is not necessary' and stop the process could be added, whenever we try
to de-hair a bird skin, or a 'you've already done this step' whenever we try to de-hair
an already de-haired skin. However I'm not sure it can be done twice on fur skins, I'm sure about the bird parts only.
Thanks
