This was close to my first thought as well. Grey thread would blend top and bottom. Simply quilt an X through the big squares and maybe a sepentine line through the sashing? Or do bubbles in the squares. But not monofilament. I know you are not feeling brave , right? But trust yourself to quilt a simple motif like X's or bubbles or squares in the squares. You'll like it more than you think. Monofilament, if it comes loose, can snag a child's toe and hurt like heck (or do damage). Plus it's a pain to work with (or can be) and not comfortable against the skin.
