And so I got them out for February's challenge and did finish several this month, but not all of them.
I finished a navy Simplicity 1590.

I finished another Mail Order 9379 made from the remnants of my Rosie blouse.

It is not crooked in reality, I had the buttons pinned wrong in the picture.
I finished my jeans, but did not photograph them, and finally I finished a Clotilde/McCall mix dress.



So as a run down:
The Challenge: Blue
Fabric: 1 yard Rowan shot cotton in coal, 1/2 yard white cotton, 1 yard sewing print cotton, 1 1/2 yards denim, and 3 yards Cotton & Steel arrow print fabric.
Pattern: Simplicity 1590, Mail Order 9379, my own jeans pattern, and an undated Clotilde/McCall 6470.
Year: Various years within the 1940s, with the exception of the jeans which are pretty 1950s.
Notions: 14 vintage buttons in navy (5), cool blue (5), gold (3), and turquoise (1).
How historically accurate is it? The patterns, techniques and notions all are, the fabrics are not, 75%.
Hours to complete: I have no idea.
First worn: Many times already for the blouses and jeans, for the dress today!
Total cost: Free, everything was from stash.
