As promised, I have before-and-after pics of one sweater's journey past my sewing machine.
This sweater was in perfect shape which does make me feel a bit guilty, but also makes me click my heels with joy because I don't lose any fabric to month holes. You usually can't tell about moth holes until after the felting, have you noticed this? and sometimes the end result is more patch than project.
In this case I got not only a full set of metal buttons but enough fabric for two pairs of mittens:
I cut the second pair's back from the sleeve cuffs, and the palm from the upper back of the sweater; that of course meant no cuff, but I was able to cut extra cuff from unused parts of the sweater's body and stitch them on. I don't think it looks too bad.
That sweater was definitely worth the three dollars it cost me, wouldn't you say?
