I'm making a cake for my daughter's 1st birthday this week and I'd like to put a #1 standing on top of it. I've made several cakes using marshmallow fondant and it works great for covering and "flat" decorations. However, in the past when I've tried to model it, it started drooping. How do I firm up marshmallow fondant? I've tried adding gumpaste powder without much luck. I've also read to use tylo powder but I have no idea what that is or where to buy it. Is it better to just make it a few days in advance and let it dry out? Help please!!

Just go buy some Wilton's pre-made gum paste at Michael's with their 40% off coupon and use that. It dries fast and hard and works great for toppers. I've made a '25' and a 'B' and plenty of bows....they worked great.

Tylose powder i get mine at cakesbysam.com they ship really fast. it does work really good. I use Modeling Chocolate for most of my decorations works incredibly good! They also sell gumpaste mix its really easy you mix 1 cup with 2 tbsp of water and after i make it than mix it half and half fondant.

I've never had luck with 50/50 fondant gumpaste. Always still too soft. A 75/25 mix would probably be better, 75 being gumpaste 25 being fondant.

thanks for the advice. i'm feeling a little lazy so i think i'll buy the pre-made gumpaste duh, why didn't i think of that before?!?
