These hoops make the process of perfect alignment easy. I have used these hoops on numerous types of materials including hooping heavy duffle bags. I have never had a failure. I don't even use regular hoops anymore. Aligning multiple shirts in the same place is why I have the HoopMaster system and 4 sizes of the Mighty Hoops. My favorite size for multiple projects is the 7.25 Mighty Hoop.
