I have a viking sapphire and while I don't have a twin needle, it does have a setting for it. I was actually looking for a twin needle last weekend as I was joining panels of a tree skirt together and wanted to hide the seam with a thin ribbon. I thougt a twin needle would be the perfect way to get the ribbon sewn down both sides at once! Didn't get to do it that way though as wanted to finish project without running to the store.
