Vintage needlework

I thought I'd share a piece of vintage embroidery I found recently when I was looking for something completely different in my storage cupboard in the bedroom. I think it's a side table mat and was stitched by my paternal grandmother who was a good needlewoman. It features a stem stitch filling skirt, buttonhole flowers on the skirt,satin stitch and bullion stitch flowers as well. The linen is very fine and features a finely crocheted edging in pearl thread. The white mark on the right side is unfortunately a hole, it looks like there may have been an organic stain on it which has been eaten by an insect over the years. I'd put it at 1950's or early 60's vintage as that was when I remember her doing this kind of work. I can't see whether it was pre-stamped or whether it was an iron-on transer which was typical of the time. I love it !
