I'm getting married in the Fall, does anyone have any cute decoration ideas?

Hey everyone! I'm finally marrying my boyfriend of 6 years!! We'll be married in October and we wanted an Autumn-themed wedding because we met on Halloween six years ago and we thought it would be nice to "relive" the night we met! So... my question to all of you is: who has some cute/unique decoration ideas for a fall wedding? Favors, invitations, centerpieces, decorations...any help is greatly appreciated!!
