Only 1 hoop, not a set.

Nurge 230-3S Flexi Hoop ROUND 17cm ( 6 3/4") SAND.
Nurge Flexi Hoops are a superb and quick way to attach your embroidery, cross-stitch or needlework fabric. They hold the tension really well.
With a stretchy rubberised wood-grained outer, the Nurge Flexihoop Picture frames are a visually attractive way to display your work. They come with a decorative hook to hang them.
You can use them by simply pulling off the stretchy outer ring, placing your fabric over the inner ring, and then stretching the outer ring back over the fabric, and hey presto your work is held tight! The inner is made from strong plastic, with an inner curve to hold your fabric tight.
