I am getting ready to quilt a wall hanging made of batiks. I plan to give to my son and his bride-to-be as a wedding gift. I will be SID and doing some hand quilting. I have read today that starching the backing will help, so I plan to do that. I'd also like to spray baste. Because I have a variety of colors and did not prewash the batiks, this hanging will probably never get washed. So is starching and spray basting a bad idea?
