Shoe Tutorial - My first shoe/box cake, very nervewracking but it worked PHEW ... I only had 8 days for it to dry, but I would suggest at least 2 weeks drying time. I used modelling paste to make this shoe. 1 tsp gum tragacanth to 225g sugarpaste. Enjoy! Excuse the little red hearts on the inside of the shoe, I had to cover the shoe brand name.
