All these pictures are created on an embellishing machine. I discovered this about 3 years ago while at art class.
Few people, I find, know about this machine. Depending on the model and make they may have between 5 and 12 barbed needles. No thread is involved.
By layering soft and thin fabric on top of felt you can create pictures. It is like 'painting with fabric'.
So many people expressed an interest I bought another 5 machines and now I run courses for anyone interested, see more on this website for details.
You can find these on this website or my Facebook page; search for Freda Harris then artist
