Pattern in Take Back the Knit, issue 2.
This is the plain version - very basic garter stitch, because it's very stretchy and done at a fairly loose gauge, it looks like mesh.
Yarn: Cascade Fixation
Needles: US 10/5.75mm
Notes: knit flat and in one piece. Size is "one size fits most" - these stretch a lot, up to a men's medium, at least.
For this pattern, I strongly recommend using the Cascade Fixation, or another very very stretchy yarn.
The vintage pattern that I used as a starting point: Lady's [sic] Mitten With Thumb, c. 1890, via the Ladies Treasury Worktable).
