Are you talking about toppers like Pink Cake Box does? The ones that are curly? 

AYes,the curly ones like pink cake box:-)sorry took so long to respond baby not feeling to good

A@Shanter no not tapits i have those and love the the bigger curly letters that on top

AI did a quick google of pink cake box images. If those are the ones you mean, I may be able to help.

It looks like she uses ropes of gumpaste to make the letters. You'll need to use a skewer both for support & for sticking in the cake. I use a grease proof cake board so the gumpaste doesn't stick while it is drying.
