Well, I bought a long white cone shape styrofoam at hobby Lobby, cut the top inch or so, (enough to make a sturdy base for the next part)and covered in gumpaste/fondant and textured it..let dry....then I got a round plastic bowl with a flat bottom, cut some window shapes and covered in gp/fondant., the sides and bottom only ( I left the top open so that I could place a battery tea light inside)....let dry. For the removable top ,I just cut a round thick piece of gumpaste and added the ice cream cones and then covered with fondant or gumpaste. Decorate as you like. I later inserted a Wilton plastic dowel thru the styrofoam to hold in place in the cake. best part, the girls got to keep the towers as night lights in their rooms. I have two tangled tower pics in my photos. Hope this helps. Have fun!!!
