We've got lot of overlap with gardening, cooking, baking, sewing, and household DIY. DH does some carpentry as well.
For more unique skills, I think a lot of my value would be in preserving food - canning, pickling, fermenting. I make excellent fruit jams and preserves, applesauce, salsa, lemon curd, pickled beets, pickled eggs, sauerkraut, etc.
I can also raise, slaughter, skin, and gut rabbits, and tan the hides. Probably transferrable if anyone was hunting, as well.
We can also help with entertainment, as we both play musical instruments. Especially if someone else is bringing the piano.
