Q1: Don't know how to choose the Hoop Length？
A1: Hoop Length refers to the length from the left bracket to the right bracekt of the regular frame (plastic frame) that comes with your machine. Just measure the regular frame of the machine to get the Hoop Length data ( Photos as reference for you)
Q2: Not sure if this size can be used for your machine?
A2: Measure the Hoop Length of your different plastic frames to see if it is the same as the hoop length in the options. If yes, the frame can use on your machine.
I love using this hoop. It is quite large and my other hoop that is only 12“ x 12“ that is not magnetic is always a pretty big challenge using it on diverse clothing items. With this hoop, it being much larger the magnets just immediately clamp on and the material is nice and tight and you can pull the edges to tighten it up further if need be, and not be afraid that the hoop will come apart. Very high-quality material and excellent performance. I could not ask for a better product for the job. I am honestly surprised I hadn’t tried magnetic hoops before.
Magnetic hoops take all the strain out of proper hooping. So easy to use! The 12.5” across hoop was exactly what I needed to do front and back full size designs and or names
Well made product - works exactly as expected - ordered easily - a tad long to wait for arrival because of no inventory in USA - overall excellent though - as a new user you have to be aware of the strength of the magnets and the force at the have when closing or connecting to the garment - pinched fingers or skin is definitely something to keep in mind as well as no contact with your mobile phone etc -- great product and cost was about half of other brands
