Jessica's Birthday Cake

For my best friend's birthday cake I was planning on making it a one layer chocolate cake with strawberries in the middle layer.  Since Jessica loves and working with horses all the time and is on the polo team I was planning on making it a grassy top with a few hay barrels and finally a horse.  The horse will be made out of model chocolate which is new for me and i will mold it around wooden spools.  I did some research on this and figured out I can make the horse and put it in the fridge so it will stay good and not melt.
