The garden gloves work pretty well, but IMO Machingers are the best - I think they grip better. I like them better than the finger cots you're talking about too, Bear - those make my fingers sweat, but the Machingers let a little more air in. I just wish the tips didn't end up so 'grubby' looking - they tend to pick up dye pretty easily for some reason and I'm afraid washing them would damage them.
Things to ask for..hmmm! Rotary blades, Purple Thang, good thread, spare bobbins... What about things like those Peels or other bobbin keeper type thingies? Clover clips - I can never have too many of those... Ott lamp? Gypsy Sit-upon? What about something decorative for your sewing room like one of those clocks that look like sewing machines? Or a sewing-related sign, maybe? A teapot or Keurig just for the sewing room? A heated footrest, for when you're doing handwork on winter days? A heated shoulder wrap for when you've done a bit too much quilting?
Are there any books you've had a hankering for? A particular pattern, maybe?
