I have a request for a hot wheels cake and saw this photo.  I LOVE the way they have the orange "track" looping on the cake and around the cake board.  Does anyone know how they may have done this?  It looks like one big piece.

Oops..........Sorry about that

AI'm positive that's more than one piece; they just hid the seams in the back and/or with the cars in the front. Use gumpaste so it will dry rock hard.

Great!  Thank you so much!
