Work Shirt, Summer Weight Denim, 1930's-1940's style

Here's some images of a denim shirt I finished yesterday.  These are after a hot soak and line dry.

This is the first time I've used my Singer 231 off-the-arm felling machine for a shirt.  Makes a great looking stitch, but the machine needs adjustment to stop skipping stitches at random.  Not yet ready for prime-time. 

Ingredients:  6oz 2x1 denim, tagua nut buttons, all cotton thread. 

Details include single needle topstitching, a tab collar, and hem gussets.
