Magnetic Hoop 3.9"x12.8" | 100x320mm for Avance Embroidery Machines

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.

Here is a photo of Double U bracekt shape, if your current plastic bracket shape is like it, choose Double U shape option directly. If not, choose Regular Shape Option directly.
