This quilt is darling!! Here's what I would do for further quilting. Go get some NEW 1 inch masking tape...don't use old. Put a piece of tape along the seamline on the top of the block. Make this tape go ALL the way across the quilt. Now put another piece of tape right below the one you just placed. Basically you have two pieces of tape with a seam between them. Now go to the outside of each piece of tape and sew straight across. Do this for all horizontal and vertical seam lines. It will be a fast grid, it will take up some of the interior of each block where there is no quilting and it should take care of your quilting needs. Good luck and smile! You're going to be a good quilter.
