Painting meditation. Abstract landscape. Add paint to a blank canvas. Don't think, just do. Mix colours mindfully. Smooth on paint with your favourite brush (I have one). Step back. Observe. Continue. Stop when it's finished. You'll know when.
Embroidery as meditation.
A piece of silk, and letting the eye guide you to create (no pre-set pattern).
It focuses the mind; the mind is solely on the making of the stitch, there's no room for anything else.
