Chocolate buttercream Basket filled with vanilla buttercream flowers

To  practice all the techniques I have been finding on Pinterest and from my class, I decided to make a cake filled with flowers. The weaving technique is very simple. Here is a picture to illustrate this:

The trick with the flowers is to do them all individually on baking paper and to then freeze it for 10-15 minutes. The flowers then become easy to place and replace in an organized way.
Then with the holes or empty spaces, I piped using the closed star nozzle to make the hydrangeas. I also piped the leaves onto the cake. It looks complicated but it is very simple.
