What size bobbin thread???
This may be a dumb question but what size bobbin thread do you use? I have a Brother PE-770 embroidery machine and it uses 40wt. emb thread on top. Should I use the same on the bottom or not? I can't seem to find anything that gives the size of the bobbin thread including the machine manual. I've been using the prewound bobbins but I have to rewind them on a Brother bobbin otherwise I get a rat's nest. I tried using Bottom Line for the bobbin and that didn't work either. If I have to rewind the bobbins, I would rather buy the spools instead of the prewound.
