How to make corners smooth on re upholstered chairs using naugahide?

Answer 1

Do you mean, it was reupholstered in naugahide? Or use naugahide to make the corners smooth? If the piece is rumpled underneath the fabric the only way to striaghten out the batting is to use a regulator, which is a 12" long needle, inserted through the fabric from the outside. You can then manipulate the batting inside. You can find them at www.mohawkfinishing.com.
