I can tell you what I have DESIGNATED to hold small stuff , and in THEORY it does. But it really depends on the user (me) to put things in it!
i call it a treasure box. It's like a brown leather pirate's chest in miniature ( about 12" long, 4" wide, 5 deep with arcing lid and metal latch. In theory it holds big scissors, thread, seam ripper, etc. I keep it close to my machine.
if I want to keep stuff that's really small and will fit in my purse or next To my recliner, it's a hard eyeglass case. It will hold embroidery scissors, small spool, needles, seam ripper, thimble, and a few clips. In theory it's ready all the time.
