Step 1: Take a blank card of any colour of your choice. We have used white blank cards as the base.
Step 2: Mix and match washi tapes of different sizes, colours and patterns. To make a birthday cake, start with the bottom-most layer and then work upwards. The tape at the bottom-most must be the longest and it reduces in length as you work upwards, giving it the shape of a multi-tier cake.
Step 3: Make as many cakes as you like. Add candles and other details with a black or coloured marker. Your quick DIY washi tape cards are ready to be given out to friends and family.
