I am making a Wedding Quilt for my daughter. The only part I was told to quilt would be the area that will Not have signatures. I have made up over 50 Blocks that will be set out at the Receiption (with an attendant at the table) for guests to sign with a pigma pen. the area where they will write their wishes will be taped off so that they only sign withing the area allowed. Then I will assemble the Blocks and quilt them. Batiks migtht still have residual wax left on them from the dying process and may not allow a pigma pen to work. But you don't want people writing on a quilted piece what if they make a mistake? it's there forever.
