Want to run up an order of canvas laundry bags for a customer ( a local hand laundry), but have a feeling can do them quickly and easily with a serger versus sewing. Only question is does one *need* a five thread machine or will four do? Am thinking a five thread safety stitch will work a treat on heavy canvas, and have heard some sergers with only four or three threads really only cope well with knits and or lighter fabrics.
Thoughts? Suggestions?
