Hi, Marianella. The name of the hoop is "multi needle monster", but in fact it IS the hoop recommended for the Brother Persona. (The name is a little confusing, but the hoops will work for the Brother Persona, regardless of the fact that it is a one needle machine.) So, the specific hoops that I recommend for you are:
Multi Needle Monster / GM1 5" x 7" (for use with arms)
Multi Needle Monster / GM4 4" x 4" (for use with arms)
Multi Needle Monster / GM7 8" x 8" (for use with arms)
Please let me know if you have further questions.
