When making my ragdoll cake, shortly after completion, the collar cracked on the centre front section . This was made from fondant.
Is there anything I should do to prevent this.
I will be making my sons' wedding cake this year and don't want this to happen, as they want it fondant covered, I am a bit concerned.
All suggestions will be gratefully received
Thanks!

You shouldn't have any problems on a wedding cake. I bet the doll's head moved on causing the cracking.
Also what kind of fondant did you use? Homemade or purchased? How thin did you roll it. Maybe you need to make it just a bit thicker.

Suzie, I tried adding CMC to fondant for the first time this weekend and I found that my rabbit character dried out much better. The fondant was easier to work with and when I rolled out the balls to make head, body etc., it was so much smoother!

Basically, I think it crackled a lot less than when I used "plain" fondant.

I find adding some GP or a little tylose powder keeps the details on my figures and cakes from cracking (which the details usually do when I use just fondant).

Best wishes with your son's cake - I'm sure it will be fantastic!!
