Wow.

I thought that my little Featherweight could just kind of go.. and go.. and go.  (Certainly it's fine with regular cotton broadcloth, which is, admittedly, the only thing I've ever thrown at it.)

Turns out elastic banding completely bolloxes the bobbin and makes it clog.  ^_^  I messed with the stitch length, the tension.. nothing seems to work.

Guess I'll be hand-sewing the ends of my elastic waistband together.  But not just now.

(Yet another reason to get a sewing-embroidery combo - automatic tension adjustment!  My local sewing friend never mentioned problems sewing elastic ends together on her machine.)
