This is such a fun topic! Thanks everyone for the input . It makes me eager to see what I can do this year, especially now we are settling into a new country and trying to get to know our neighbours..!
Last year I made these cute little packages that went in the mail. Not edible, but kitchen made

. A little more than 'just' a Christmas card, and they were very well received.
They have a tiny beeswax candle, a 'wax label', which is scented with essential oils (you could also experiment with whole spices) and a little tin of hand cream. Everything decorated with stuff we found in the woods (except the grapefruit slices, sadly.

) and packed with some 'woodwool'.
I made them with my kids, who loved it. We made them as a relation gift for an company and even made a little money on the side, even though it was ofcourse way to much work.

I'll probably never do 140 again, but it was a lot of fun!
