I love wedding favors, I like the small details at a wedding. They are not a necessity, the favors can be left out. It just depends on what's more important to you.
With fall just around the corner, I know there will be a lot of fall themed weddings. I found some great favors ideas, to fit that theme.
These caramel apple favors are great, & you could even do these yourself!
Here is another idea, you could even buy the jam already packaged & then add your own personalized label.

Here is a jar idea, that you can fill with your favorite lemonade mix or hot chocolate mix.
Even if you aren't having a Fall themed wedding, these favor ideas can be used for any wedding.
