Hiya,
I am veeeery new to cake decorating. Will be decorating some cupcakes, with royal icing topers/deco. Since royal icing is too sweet and ppl normally will scrap it before eating the cake 
, i was thinking to crumbcoat the cuppies with butter cream and top it with a layer of royal icing. however, since oil will normally 'destroy' royal icing:
will the royal icing melt/loose it's shape? or worst, the color would run?
Sorry if the questions sounds silly.......but if i dont ask, i willl never know!! 
Does BC not work well with RI when the wet RI is applied directly to it or when dried RI accents are put on the BC?
......since oil will normally 'destroy' royal icing: will the royal icing melt/loose it's shape? or worst, the color would run? ........
......Royal Icing and buttercream usually do not mix well......
***YES!***** RI items CAN be placed on b'cream.
For the most part there will be no problem -- **if the royal has been properly made**
It must be beaten until it stands in stiff peaks. Using a hand-held mixer this will take 7-10 minutes. Using a KA and warm water it will take around 3-5 minutes.
ColorFlo items can be place directly on b'cream.
RI flowers can be place directly on b'c too 
If the flower is thin - like say an apple blossom it can absorb some of the grease, soften a bit and turn color slightly but it willnot melt into a puddle! Roses are no problem because the are soooooo dense.
. Thank you all so much for sharing.
In my experience, dried RI decoration on BC are not a problem.
But if you have to refrigerate the cake because of the filling, when you bring it out of the fridge, condensation forms, and THAT can mess with your RI. I made some butterflies whose wings "fell" when they were on a chilled cake and brought back to room temp...
I did a royal icing plaque and let it dry for 2 days and the put it on buttercream. I did notice some spots where the butter was coming through the plaque, but I also didn't let the buttercream crust either. I wrote on the cake with RI and it was fine.
