Excused the randomness of this post, but I just wanted to share with you some ideas I've used over the years that are simple enough anyone could duplicate.
This is one of my favorite things to use as a cake topper especially for wedding cakes. I like it because you can color it to match any color scheme and it can be a memento the couple can keep and use in their home. It's simply a wooden letter (about 4" or so high) that you can get at any craft shop. I just painted it and hot glued it to a dowel rod.
Names on cake
I was really happy with the way this turned out. My family spent a weekend at the lake with 2 other families so I made a cake for us and I decorated it with all of our names. The names are written in cursive around the cake. Granted I don't have the neatest cake cursive writing, but I just love how you have to do a double-take to really see the names.
I used this for a friend's groom cake. It's chocolate that I broke into pieces and just stuck to the side with frosting. I also added chocolate shavings to the top.
