2 Pinocchio needlepoint art

These come from a storage auction and are not yet framed. I am not familiar with the hobby but the canvas seems to gotten dingy around where it gets stretched while working on it. They were also stored in a stack, folded. Not sure if there is a process for cleaning them like how u iron them to get creases out. The larger canvas is 12"x12" and the smaller is 6"x6". I have quite a few so message me for questions or to combine items for discount.
