I have a Husqvarna Viking Designer Diamond and would not put it on a portable table. I know it would vibrate like crazy when embroidering. I have it on my built-in countertop in my sewing studio. I have a Gidget II and a Sew Ezi table and find they do vibrate with a heavier machine on them when sewing at a faster pace. A sturdy kitchen table or something along that line would be my choice for an embroidery machine.
