Loosen the outer screw, lay the inside hoop flat, put the cloth on the hoop, then put the outer hoop on the inside hoop. Inspect the hoop whether it is tight enough. The way to check the tightness is to use a needle with thread going through the fabric surface.
This product would be ideal for crafters who enjoy cross-stitch projects, particularly those who enjoy working in a smaller hoop, as the Round Embroidery Cross Stitch Plastic Ring Frame Hoop size 2.9" and 3.6" offers a convenient and comfortable space for detailed work.
