Whenever I do a crosshatch on my sewing machine I get a little movement of the fabric. I think I would baste well or use 505 to reduce slipping. If you do the circles first and then try to do the crosshatching, you will probably get little tucks when you get to the quilted circles. I might be tempted to do the circle outlines first and then quilt different size circles or bubbles in the background. Cute top!
