OK, this break, I decided that having two sewing machines in my house and no clue how to use one was unacceptable. My smallest goal: to be able to do some stitching on paper crafting. My largest goal: make an article of clothing. My need: to figure out how in the h3#l to get the mechanism to do what it is supposed to do.
I looked for video tutorials, but, even though they said they were for "beginners," there was a lot of hidden lingo and assumptions. Plus, even though machines have similarities, they are not all the same.
My next step was to search Singer's site for the manual for my machine. Success! It is a free download... $15 if you want a hard copy. I did print it myself, as reading online while looking at a sewing machine is a bit challenging. Now, I am off to figure this out. More to follow.
