who will have a normal household sewing machine with the thread of the four threads have no problem, but it's really very little space for the hands, you need to thread a tweezer (which is in the accessories :) since Toyota only one sting can (needles in variety 4 or needles 3 :) and the popular t-shirtsaum also should not :( you see an overlock only as an accessory, without reasonable normal machine does not come from you! Given what Overlocks otherwise cost is a real recommended purchase !!!! AND it saves so much time, since they practically three abeitsschritte makes in one!
