lol... I couldn't think of a better way to word this topic.
I often see examples of a really neat way of lettering, here are a couple of examples:
Is there a technique to do this, or just roll out your fondant and do your best?
Roll the fondant and do your best. You could try using a piece of paper with the text on it underneath the parchment paper to use as a guide. Just make sure the letters are well dried before trying to stand them up so they don't break.
if the letters are standing on top of the cake, i would use gumpaste (or a 50/50 mix with fondant) - its much stronger, and will also dry much faster (either insert supports like toothpicks, skewers etc when soft, or glue to back with chocolate/ royal). for letters sticking to the cake, because they dont need to be so strong, you can just use fondant.
if you have an extruder, thats the best way to get long sausages. otherwise, roll it out, and finish by using a fondant smoother to gently roll it - evens it out wonderfully!
very well dried...takes days..not hours just make sure you do this days ahead of time, waiting to do it even one day ahead of time these letters will not be dry enough to stand up. **Love the sample you showed with the name on the side of the cake** sample two
