Okay well then "who" is the fae. Give me the basics. Not the folklore, but what is beleived of them in real life.
leave out some milk, cheese and small clothes, doll clothes would do, or you might upset the Brownie who cleaned your mess.
Milk, cheese are good ideas but clothes aren't. Brownies and many other kind of fey who can be found in human houses tend to find the gift of clothes an insult or a disrespect and much prefer their own clothing, no matter how tatty it may appear.Also, don't leave out too much food, this can interpreted as an insult as well.
Correct me if I'm wrong here............. but not all fey are tiny.
