How to make sprinkles stick to hard frosting?

[Dandelionchaser]

For DD's birthday I bought an undecorated cake with white fondant icing, and I bought Frozen figurines and candles and was going to cover the icing in silver/blue sprinkles, glitter, silver balls etc. I've got the cake home and it occurs to me now that the sprinkles will just roll off because the icing is, obviously, not wet. How can I do this? The two things that came to mind are pressing everything down a bit and risking fingerprints, or maybe spraying with water first or something? Please help I've never decorated a cake in my life

Make up some water icing (icing sugar and water) and spread that where you want the sprinkles. They should stick well and it wont affect the fondant icing.

I was going to say edible glue. But actually I'm not convinced it's not just sugar syrup mix! As pp described I'd try that first before the edible glue.

This is what I was going to suggest.

Mix some icing sugar and a few drops of water to make a paste, spread it over the top and chuck sprinkles etc at it

OR

Make a buttercream icing/ buy readmade 'frosting' and some piping bags and pipe the buttercream/ frosting on top of the fondant icing decoratively and then chuck glitter at it.

Thanks for the help, I'll try the icing paste!
