Not a pattern for fabrics, but one produced from a jpg of a stack of fabric items that was posted on Pixabay. The tile that this is based on can be had by selecting the rectangle in Inkscape and using shift+alt+i.

Mostly just mucked about with the colours and made one of the paths in the lead frame opaque. The glass remains transparent.
