I have been asked to make a cake like this: 

I am just looking for some advice on how best to make the stork and the banners.

My plan at the moment is to make the cake, and cover in a baby pink buttercream.

So far for the stork my plan is to maybe get lollipop sticks, create the body first and attach to the sticks, then make the head and beak and attach using toothpicks? Then for the baby on its beak I am unsure on how best to make and secure this? 

For the banner - I have seen you can purchase cutters that create the triangles but does anyone know how best to cut out the letters? I can't seem to find any alphabet cutters that seem small enough. 

Is it also best to make all of this out of gumpaste? Rather than fondant?

For the flowers I will either purchase real edible ones or just buy pre made fondant ones. 

Thanks
