Back to the topic, my initial plan was to use fondant for the strips but due to lack of time, I cheated using frosting sheet. I printed out the design that I want cut it based on the diameter of the cake and have it pasted on the cake. This includes the picture of my future sister in law.
This method is nothing new really. But for everyone's benefit, I did a simple step-by-step photos on how to stick the sheets to the fondant.
1. Prepare your cake and the sheet that you will be using. Here I used a small strip of colorful stripes
2. Brush the area which you want to paste the sheet with water. Have a small brush ready to touch it up after pasting it
3. Gently paste the icing sheet on the cake. Use a small brush to touch the corners that are not glued nicely to the cake
4. The end product !
Happy trying !!
