Reference for Chullin 246:28

עור טמא מדרס חישב עליו לרצועות וסנדלים כיון שנתן בו איזמל טהור דברי רבי יהודה

R'Jeremiah raised an objection: IF A MAN WAS FLAYING CATTLE OR WILD ANIMALS, CLEAN OR UNCLEAN, SMALL OR LARGE, IN ORDER TO USE THE HIDE FOR A COVERING, UNTIL SO MUCH [OF THE HIDE HAS BEEN FLAYED] AS CAN BE TAKEN HOLD OF, etc. Now if more than this had been flayed it would be clean, would it not?
