Such a beautiful redwork piece!!! It is stunning :D:D:D
I would hesitate to use basting spray, it could make the color run, and possibly set it. I would be more tempted to quilt it as is, and then gently wash it using color catchers and maybe Retayne or another product. If the seams are off now, they could further distort and quilting may help keep them in line. Just my 2 cents worth :wink:
