The walking foot.

When I started the yellow hat band there was some strange clunking and the material was not going through the foot as expected !! After a bit of checking the foot discovered it was not seated correctly !! The foot worked fine once it was seated. Pleased this happened before I started quilting the costume :-)
For those that may wonder the piece of metal behind It's a quilting spacer that attaches to the walking foot.
Theoretically it should save me marking the material with Taylor's chalk or a removable making pen.
