A quilted pot holder with a hanging loop, folded in half, button applied to catch the loop.
Inside use a Sharpie to neatly mark off sections labeled with your most used needle sizes.
If you also sew a couple of slightly overlapped, on the closed end, zipper snack baggies - one facing left open, one facing right open - down the middle of the opened pot holder, and cover that seam with a thin pretty ribbon, you will have a carrying area for thread and scissors, too.
