Need your help. I'm new to cake decorating. Is it okay to place royal icing drop flowers (dried) on pastry pride? 

Thank you all in advance.

I don't see why not.  They may soften a little if the room is warm, but should be all right for several hours!

Thank you!

As I remember they will soften - maybe even to the point of becoming a puddle :(  The smaller, thinner the royal flower the more trouble it will be on Pastry Pride.

You might try adding a thin coating of melted white chocolate to the back of each flower or put a drop of melted chocolate on the cake, then add the flower.
