The fingers can be knitted plain or stranded; the instructions include both versions. Stranded fingers are less stretchy and may fit a little snug, especially if you have larger hands. If that's the case, I recommend knitting fingers in solid color, or using larger needles.
The PDF has multicolor charts, but as you can see on the photos, bicolored version looks nice too.
