The fae are shy creatures, made so by years of mistreatment and misunderstanding by humans. They are jealous of the physical world which contain the living, breathing, trees and plant life they so love and have so carefully reproduced in their own world. Our callous treatment of nature infuriates them.
You must work first to win their trust. Plant a faery garden as a refuge for the little folk. Leave a corner of it wild and uncultivated. Leaving out gifts of food and treasures for them is a good first step. They love ground ginger, barley, sweets, cream, and anything that glitters. Also clean water, butter, wine, honey, and bread. Never toss out faery libations like you would food for wild animals. They consider this very disrespectful. Make up a little basket of your offerings and leave them on your step, in your garden, or under a tree.
Favorite faery stones are tiger's eye, peridot, jade, lava, fluorite, and especially emerald. Don't expect these gifts to disappear, as faeries are able to extract the spiritual essence of our physical gifts to them (so be sure to leave them in love and with deep respect.) You will, however, have to replace these gifts often in order to keep the faery folk hanging around.
