The Stitch EZI FRAME is an innovative product. The 6 inch (15cm) frame is 25mm deep and designed for embroidery, cross-stitch, candlewicking and wool embroidery. It can be easily adjusted for various fabric thicknesses.
I can personally endorse them as I was given one of the 10" frames one for my 12th birthday and I have stitched all of my counted cross stitch pieces on it for the last 40+ years. I have tape around the inner ring on mine to give it more grab. It is a fantastic piece of stitching equipment.
