Happy Birthday Cake Topper

First you need to find the font you like, lay it out how you would like it to appear on the topper. Then you need to create an offset behind the words. 

Once you have done that, create two rectangles the same length and join them to the offset, where you you would like the legs to go. Then you need to weld the offset and the rectangles together. The rectangles become the legs that go into the cake. 

Once your topper is ready to go visually, you can cut the background offset with black (or your desired colour) and then the words in white (or your desired colour) and glue or double sided tape them onto the black background and bingo! You have your beautiful new cake topper!
