Bean to make my tent I used 3, 6" round cakes so if you need larger you will need to adjust sizes
Cut a 10 round circle from poster board or card stock. Cut a slit half way. Roll into a cone. Use your pan to check and see if you have enough over hang for your tent.Tape or staple I then covered the cardboard with parchment paper. Then roll out a circle of fondant (mix withe tylose!) the same size. Drape over your cone template and trim around the bottom. Let dry a day or so
Bake, stack, fill and ice your cakes. add stripes in contrasting color.
Gently remove top from your cone template and place on top. Secure using some buttercream or royal icing.
Now you can use your cone or trace another paper circle and cut a pie shaped wedge. Use your stripe as a guide for how wide it is. Use this wedge as a template to cut out fondant. Gently apply fondant to cone lining up with the stripes below. Start from point smoothing downward. Trim bottom if needed.
I added the scalloped edge by cutting circles in half and attaching hem with piping gel.
Hope this helps and makes sense! Lol!
