Back from son's wedding. I have the quilt top where everyone signed and am getting ready to quilt it. I was told to iron the writing to heat set it. Is that all I need to do or are there any other steps or suggestions? Don't want them to fade or wash away. I am using fusible batting so it will be washed at least once. Thanks for any help. BTW, the top is scrappy and will actually be the back. I am doing the quilting from the back like a whole cloth with a wedding announcement type theme, hopefully will turn out how I envision it.
