When I used to think of an embroidery machine with 10 needles I assumed that more than one needle would be embroidering at a time. So say there was red in the right corner the machine would be doing that and in the other corner were the green was the other needle would be working on that and say yellow in another part of the design. Well I guess I am not the only one because many people say they thought the same thing. Just to clear this up a commercial embroidery machine only embroiders one needle at a time. A commercial embroidery machine will embroider faster than a home machine and it will change the colors for you but it only embroiders one color at a time.
