I used a sponge to apply Stewart Gill fabric paints to my 'printing plate', then pressed it onto the fabric.
I chose some really pretty perle embroidery thread, which I have been hoarding for ages, and started to embroider over the printed design. Only two stitiches - seed stitiches and french knots.
Once the hand embroidery was finished, I backed the lightweight cotton fabric with heavier fabric, and machined a small zigzag stitch around the edge. I like the finished postcard, not at all my usual colour palette, but summery - which is more than I can say for the weather!
