( So drag out the old manual (which in itself is a miracle that I can even find it as I DON'T READ MANUALS!)
Same here although I keep the manuals to my machines with the machines. So do I open them and read them? NO!
Was a little embarssing when the sewing repair guy left a note on the Pfaff I brought in for repair, note said "Read your manual". I had upgraded my old Pfaff for a newer model but couldn't change the feet, turned out if I had read the manual I would have known that this newer model required me to push the even feed lever back to change the feet.
If I didn't make mistakes I wouldn't learn anything new and believe me I'm learning new things every day.
