This is the decoration on my Grandma's 80th birthday cake. I decided I wanted to make a stain glass type design. The biggest challenge was getting the outline on the cake. I tried a FBCT method that did not work real well so I ended up free handing the black outline. The colors are piping gel that I made and colored and then I used a paint brush to fill in the areas. Grandma refused to let me cut into the stain glass part of the cake. Hope you enjoy!
