While my younger son was ill, I needed something to persuade him away from only electronic stimulation. Rummaging in a cupboard, I found some of my family's old Spirograph kit and some of my Spirograph compositions, dated 1971.
These have inspired some stitching on to the centres of the long-term Dresden plate project.
Initial testing with washable fine marker pens
Three Dresden plates with hand embroidered centres ( back stitch and French knots) using Rainbows thread, expensive, but worth it.
