It reminded of a wallhanging I made last year, which unwittingly prophesized the event:
I used the same idea years before, for this matzoh cover. The four corner moons were cut from streaky batiks - purple, magenta, lavender, and orange - plus the central one, of course, from trompe l'oeil matzoh fabric (no financial affiliation).
Stamping is another way to make moody moons. These were stamped with fun foam, the thin foam that kids play with, cut into circles. By not refreshing the fabric paint with each consecutive stamping, you get an interesting gradation among the images.
Thread painting is another way to go. Stitch heavily with metallic and holographic threads over an appliqued circle. (Pretend this is an orange moon instead of a blue/green batik sun. Close enough).
I am a huge fan of superstar quilter Carol Taylor, who has made both moon and eclipse-themed quilts, shown off on this page. Check out especially the quilt titled "Moonshadows" and "Eclipse #2."
Have you made meaningful moons?
