Nearly!

The groom now has his wing collar and his cravat.

Good news: I went to the cake supplies shop this morning and bought some 'pulling bows'. They're great! It's ribbon which has a string that runs through the middle. You pull the string and it pulls the ribbon into a bow! Fantastic!!!

Bad news: I don't think they look right on the cake.

Righteo.... all I need to do is give the bride some hair, decide for once and for all what I'm going to do about the bows and then it's all done.
