Holice, I am so glad you posted this. I am in the process of hand quilting your Welsh Beauty right now. I bought a grace 44 frame when I bought my quilt top because I had ask this same question about spray basting before hand. I hope others see and follow your advice.
On a side note. Do you know if you will be designing anymore in the future? I can't wait to finish this one and start another. All your patterns are lovely.
