Last week I had my Sewing Machine serviced by the
(he even makes house calls).
He taught me about my machine, and how to keep it "tuned up".
The man is a miracle worker. Bessie Higginbottom has never sounded better.
He took all of the removable parts off, and all of her innerds were showing.
Then he showed me how to oil all of the moving parts (every 6 months)
with WD40 (really!)
He also told me to oil the bobin race every day that I sew.
Here are a few other tutorials on Machine Maintenance:
New Mexico State University-this on also teaches you about getting a good tension.
Get those Machines ready...and Make sure that you have some good needles handy.
(I only broke one this time!)
