This guide goes over how to change needles in the embroidery machine.
Needle type: DBxK5
Default needle size, supplied by Open Works: 75/11 sharp or ball point
You can bring your own needles, but they have to be type DBxK5. If you use your own needles, replace them with the 75/11 needles before you go.
Tools: flathead screwdriver (There should be one in the utensil holder at the Embroidery machine work stations.)
Tip: If you can't see the groove, feel for it with a fingernail. It will catch your nail in a way that the scarf doesn't.
Tip: You can use an alignment magnet to confirm that the needle is oriented correctly. The magnet is found in the upper drawer of the tool chest and will stick to the needle. Make sure it settles on the grooved side of the needle and points 0-5° to the right. If your body is centered on the needle, this will be approximately midway between your center and your right shoulder.
If you use your own needles, reinsert the 75/11 needles when you are finished.
