My Must Have toys are:
the Black Handle Scissors--yep, The Scissors No One May Touch, under penalty of death or worse,
a hem gauge I've had for a zillion years (metal, 6", has red slider, hmm, says JCPenney Handee Gauge--how old must that be??),
equally old seam ripper,
and an artist paint brush (1/2" ox hair) that I use to brush out the feed dogs, bobbin case, etc. It's the greatest thing. . . I've had it so long that the handle has a really pretty patina to it now.
A couple of days ago I put Sidewinder on my Dear Santa list. Glad to hear it works!
