I recently found a linen napkin in an op shop that had a very worn cross stitch flower motif in one corner. It also had a nice decorative pulled hem. I bought it for two dollars, unpicked the motif and washed it. Then I embroidered the heraldic seahorse from my device in stem stitch in one corner.

I also ran a purple thread along the decorative pulled hem for a subtle highlight.
