What advice would you give someone starting this project? In your embroidery software, make different size boxes. The needles you have more on hand will have the biggest boxes. Then label the boxes with the specific type of needle. Make it more interesting by decorating the lines of the boxes and putting some of them vertical. Put a handle on it if you plan to hang it. Stuff it with polyester stuffing and there you have it. An organized machine needle pillow.
