This is a high quality wood embroidery hoop, made by Elbesee in the UK. Because of its extra nice hardware, it can open wide enough to hold most flat needle felted pictures, as long as the wool is not too thick at the edges.
This is the same hoop that we include in our Painting with Wool and Coloring with Wool kits. Now available in 6 inch, 7 inch and 8 inch. 7 inch is the size we use in the kits.
