Nova's Featherweight 221 Maintenance Card
From Nova Montgomery, who teaches a nationally acclaimed maintenance workshop on the Singer Featherweight machine:
"One side features full color photos of common things such as correct threading, correct needle placement, etc.
The reverse of the card features troubleshooting prompts such as "machine won't sew - won't make a stitch," "skipping stitches," "motor runs, but machine does not operate," etc. with bulleted items to check and correct."
These cards are heavy duty laminated and designed to fit right in your Featherweight case.
