Have not posted a picture of any of my pieces before, so will give it a try. Surprisingly the preview doesn't show actual picture, so hope it is OK. Not sure how to enter it in the gallery section.
Starting with a simple shaped sycamore hollow form, hopefully I enhanced it with colouring and cut-outs.
Piercing bit with micromotor used for cut-outs before sanding. Outside airbrushed with transparent acrylic paint over white gesso primer; inside brush painted with dark blue then light blue added with sponge for a speckled effect. You can only just see the heart shape on RHS !
