Well, I have a few ideas together.
Food items: Cordials, Chai Mix, Salted Caramels, Sour Gummies, Pecan Pralines
Photo Books/Calendars/Etc: not fully handmade, but involves effort
Advents: I like the tea idea, but am also thinking of making some humorous ones. will also have to look up this new years resolution calendar mentioned in the thread.
Sewing: considering indoor tents for the kids and sleeping bags, maybe hammock chairs as well. Costumes/Dress Up items always good too, scarves for some of the adults
Plants for neighbors: narcissus idea, maybe succulents or cactus
Lotion Bars and Kids Soaps (with legos or dinosaurs, etc)
I'm sure there will be more, but just wanted to get some ideas posted.
