Table Tennis Direct

I recently bought two sheets of rubber brand new from direct table tennis. Com sponge thickness is 2.00 mm and I did not know at the time of ordering the new rubber sheets were going to be too big for my bat I do not anyones I need help immediately

Either trace around the bat to put the form on the rubber and cut a little smaller or go round to put it together, then with a sharp knife, as you would for a pie dough and cut excess
