I have a ULT Brother and my small hoop is 4x6 inside. A design has to be 3.98 inches or smaller to work in it. I don't know if your machine is the same, but your machine should show you if it fits or not and if not I can make it smaller or larger to to a certain degree. Most designs that say 4x4 are actually made to fit the 4x6 hoop and are alittle smaller.
