Hmmm - how do you categorise?

Hi lovely Folksy folks… bit of advice please…
I’ve been making wee matchbox messages that don’t seem to fall into any real category. What do you think is the best category to put them in so that people will find them?

They are very cute and I see them as an alternative to a card, so perhaps in greetings cards ? But I would mix it up a bit, some in one category, some in another.

I think there is a keepsakes catagory - might be worth putting some in there
