How do you all cut cake slices to specified sizes without busting out a ruler? I want to ensure that I cut it accurately to ensure enough peices for everyone as it looks like will the designated cake cutter!

Bend your thumb. The space between the end of your base nail (end of your actual thumb) and the middle of your first knuckle is about one inch. So you DO always have a ruler with you!

You can also put little marks in the design to mark where to cut. I do this on sheet cakes. Just a simple dot or a fancy twirl in the border design, every 2 inches and you're set to go!

Once you cut 2 or 3 cakes, you'll be able to eyeball it, no problem.

You can also practice drawing 2 lines two inches apart on a piece of paper ... draw the two lines, then measure them to see how close you are. As we say in the trade, it's "a piece of cake"!

Indydebi, you're brilliant! Thanks!

I also use a long serrated knife which is about 1 inch wide. Measure and cut all at the same time!
