Is it possible to put them on my cake a few hours after i make royal icing flowers? Or how about a day? Or do i really need a lot longer?? They would be roses and small drop flowers. Thanks.

I would give the flowers a few hrs to overnight (I let mine dry overnight) but if they can be handled in a few hrs no reason not to go ahead and decorate, I just trust and plan for overniters in my area and weather of the day,

THANK YOU!!!

It depends on the flower. I made some violets today and they dried in less than 1 hr. Roses take overnight - again depending on the size.

You can speed up drying time by putting the in an oven with just the light one.
