"A gadget is a gadget only until it becomes essential." That's what I tell my husband anyway.
I agree that Gingher scissors are the best!
A double curved pair of scissors for clipping jump threads and applique scissors. I thought the applique scissors were an extravagance until I used them. They really do make it easier to remove fabric around applique and to remove excess stabilizer when the project is done.
Small rulers that will fit inside of the hoops for centering.
Blue wash away marking pen (I've had trouble with the purple ones).
A bulletin board behind my machine for the printout, color chart and other notes I make in the design stage.
And a comfortable desk chair. I scrimped in the beginning, but if you think about it, you are going to spend a LOT of time in it and your back will thank you if you get a good one from the beginning.

p.s. After reading the other posts, I'm going to have to get one of those sidewinders!!
