My daughter and I worked on making it together and here is our version which is very similar. We've used a few retired items to make this one, but it was worth it.
For the inside we used the Birthday Delivery stamp set and stamped the cake which Emma coloured in, and added the sentiment which worked perfectly for her friend.
We also found a unicorn gift to go with it so I'm sure the birthday girl will like it.
