Have never used a longarm quilter and don't know how to take my quilt top to her. It has been suggested to me that I let someone do the quilting of the 2 quilt tops that I have finished. Do I stack the layers and baste them, or does the LAquilter put the stack together with me supplying the backing? I have only done stitch in the ditch, but want something nicer for these quilt tops call for it. What is a reasonable price to have this done? Each quilt top is for a queen sized bed. Thanks for your time to answer this.
