Any idea how should i decorate a cake ?

Hello. This coming sunday will be mother's day. There is a shop at my area which allows people to decorate their own cake with the provided fruits and cream. I am going to decorate one for my mum. However I do not know how should I decorate. Please help....

Oh and, I want to decorate for my crush too. Any idea ?

hmm, well id say giving your crush a cake is a bit much
usually justa simple hello, I like you will do
as for the cake
try to think of things your mum likes
like an animal, a car ect
if she likes a chartity like the breast cancer foundation or something
and you can arrange the cream and fruit into a shape like the ribbon for breast cancer
or an animal
or object
or/and you can write letters with the cream and arrange the fruit into letters/numbers as well
