when done cool on rack for 15 to 30 minutes. while it is cooling mix 1 and a half jars of frosting with blue , black and violet coloring until its the navy blue color .
Then put the 1 cake on a board (I used a cake board they were cheap at craft store). Cut a v shape out of the neck . then take the other cake and make the sleeves to use on the jersey
Then put it together. Then Ice it with the blue icing and I used the red icing to out line the number i used some of the white icing to fill in the out line of the numbers. i mixed some silver in the white icing to make a silver color to use on the sleeves
