Stained glass quilt stars

Stained glass by Dave Roach

We still have a few older windows that need to be replaced so they get plastic put over them for the winter. I recently noticed that when the sun shined through the stained glass that was behind the plastic, the plastic distorted it enough to make quilted stars appear where there are usually squares. Below is a photo of the piece without the plastic over it.
