Actually it was me that matched the bobbin thread....and not expensive at all. I used empty bobbins and wound the colors I needed by hand (fine for one towel). If I ever would need more, I would buy metal bobbins and wind my own using my sewing machine. I just used the embroidery thread.

I only use material thickness #5 and do very well off my inexpertise eye. I will try with higher number to compare. Anyone have another images? Someone, I think Roland, say that he matches the bobbin tread with the upper thread, that sound very expensive since the minimun quantity i bough was 144 bobbin white RA.(very good).
