I was wondering how you do this? Do you leave the paper towel roll in it and place it on the cake? Or do you somehow without breaking the fondant, get the roll out. If you take it out-how do you do it without breaking the fondant?
Thank-you for your help!

Hi there, I have done a castle cake and this is how I did it. I didn't use fodant. I used Pastillage. First I wrap the paper towel roll in clingfilm/saran wrap and then I dusted it with some cornflour/cornstarch. Then I rolled the pastillage and covered the paper towel roll with it and stuck the two edges with some edible glue. You have to leave it to dry completely. When its dry you can take it out easily but carefuly. I learnt this from Lindy smith's Celebrations cake book.

Then I used Icecream cones as the turrets. I covered it with gumpaste using my sugar shaper.

If you look in my photos, it will be much clear to you.

I did the turrets on my castle cake (in my photos) by wrapping the fondant on to the paper towel roll with royal icing and wetting the edges to seal. It was really easy, no removal of the cardboard is necessary. This was one of the most fun cakes I've done...good luck with yours!

There's a great tutorial on cakeboss.com

I used debbie swiss rolls for my turrets. I skewered them vertical and then covered in a very thin layer of buttercream and stuck the fondant to that. I'm always about things that are edible

Cool. Thank-you for all the ideas!

That tutorial is great! Thank-you!

You have to make sure the buttercream smooths out the edges. The way I did mine was a stone effect so I put little globs of fondant on here and there. But if you want a more solid look, according to Debbie Brown you roll the fondant pretty thick to add structure to the turrets. I used 1 wood skewer down the middle and 2 toothpicks horizontal to keep each turret in place.
