In this clip, an excerpt from his video Altered Forms with Textured Surfaces, Bill Wilkey shares a great solution to this challenge: a handbuilding technique! He handbuilds his square lids with a slab that is slumped right down into the jar itself creating a nearly perfect fit that requires minimal tweaking - much easier than trying to throw and alter the lid.
