For most cookie exchange parties, the host will set up the party much like a potluck: she will decide how many cookies each guest brings (typically one dozen per guest), and even assign cookie types if desired -- one guest will bring chocolate chip cookies, another will bring sugar cookies, etc. Guests can also be asked to bring copies of their recipe to share. The host will also manage dietary restrictions or other considerations. On the day of the swap, guests will bring their cookies and the host will set them all up on a large table, next to copies of the corresponding recipes. Guests can mingle and enjoy cookies and other refreshments, and at the end of the party they can take home some of each cookie!
