I hand crafted these cake toppers from gum paste. They can take a couple of hours but the result is always a fun reflection of the couple. My friend Karen Hill at Wedding Cake Art Sydney, makes these and also runs cake decorating classes.http://weddingcakeart.com.au/
If you want to keep your toppers long term though, I suggest you buy plastic or ceramic toppers as the sugar ones will deteriorate over time. Have fun with it. Or just be traditional.
