Two quick tips:
1. As I was walking by the American Cancer Society Discover Shop in my town this morning I saw a stunning cranberry-red evening gown in the window and immediately thought it would be beautiful in a formal autumn wedding, for either a maid of honor or an adventurous bride. The California shops are having a Fall Preview/Summer Clearance sale at the end of August. Who knows? You may find the dress of your dreams and help a good cause.
2. Target has mini-lunchboxes filled with candy for $1 each. The outside pictures are Toosie Rolls, Double-Bubble, Now & Laters, etc., and each box is filled with that candy. These would be adorable favors at a candy-themed or Halloween-time wedding.
