Step 1. Bring out your antique sewing machine to hem the curtains you just bought for your new Swiss apartment, all of which are roughly 3 feet too long for the windows.
Step 2. Realize that the sewing machine plug, having been manufactured in the U.S. along with the rest of the machine, won’t fit the Swiss electrical socket in the wall. Briefly consider hemming the curtains with Scotch tape.
Step 3. Remember that you have a spare U.S.-to-Swiss plug adapter lying around somewhere. Locate it and affix it to the plug end of your sewing machine cord.
Step 4. Plug into wall. Hold breath, and then switch machine on.
Step 5. Watch as sewing machine light comes on, and motor whirs happily when pedal is pressed. Voilà!
Step 6. Proceed to sew. Notice that the bobbin winder spins much more efficiently than usual and that the sewing machine light seems more intense than usual.
Step 7. Chalk it up to your wild imagination.
Step 8. Think that maybe you smell burning, and might be able to see wisps of smoke coming from the sewing machine light.
Step 9. Chalk it up to your wild imagination.
Step 10. With a sharp popping sound, simultaneously fry your sewing machine and blow a fuse in the dining room.
Step 11. Sit in the semi-darkness and Google international power plug standards.
Step 12. Realize that U.S. plugs have a 120-volt electrical potential, while Swiss plugs have a 230-volt electrical potential, and that therefore, a transformer is needed to safely use the handy-dandy plug adapter.
Step 13. Sew the rest of your curtains by hand, and begin saving up for a new sewing machine.
