making my first skegs, bill of materials? Foil?

so, id like to make a couple box type woode skegs for a longboard. id like to make a d-fin and a hatchet-esc type skeg, problably around 9-10"

so i was wondering how much glass cloth i should get, how much resin, what type of resin, and how i should foil the skegs to yeild good results.

i realize that foil is a largely debated issue, but im just looking for a good starting point. Thanks!
