I too am in the favours, take em or leave them camp.
That being said, I did end up having favours for my wedding.
My guest list was so small (45 people) that I was able to splurge a bit on the gifts to others.
I had about 6 kids at the wedding, so each one got a basket of neat stuff (simple toys, colouring books and dolls, stuff like that.) made them feel important, but also they got to have fun while all the adults were busy. Plus they had a bowl in the middle of the table with about 120 coloured pencils they could use, then divide up after.
I made all my table decorations. rectangular vases, filled with assorted coloured stones and aquarium gravel, with 1 large pillar candle in the middle. 8 tables, each had 3. None left at the end of the night. (I had told people to take them if they wanted them)
Also made topiaries (dowling, plant pot, foam, foam ball, and those small fake roses) same number as the vases, none left at the end.
And then the actual favours for each person were small metal buckets, painted orange, with our names and wedding date written on in gold sharpie. Filled with popular candies (werthers, mints, chocolates) and 3 small unscented candles. Again, none left at the end of the night.
So, I guess that most of the stuff I did was useful in the end (the vases were very pretty, the topiaries were just cute, and who doesn't love candies and regualr candles? Plus, the bucket only had writing on the one side, so turn it around, and no one's the wiser.
