Lovely quilting!!!! The one and only time that I tried the black light to quilt white on white, the light picked up the white design on the fabric to the point that I could not see the quilting thread. My solution was to place a trouble light at the end of my quilting frame and let the light "wash" over the sufface of the quilt from the side so I could see the texture of the thread to see where I was quilting. Very glad to see that the black light worked for you.
