You could use Royal icing with the thinest tip like a 00 or 0 or 1 or you can use piping gel...

would i be able to use buttercream?
thank you, kika

I was told that Fondant and Buttercream dont play well together so I would say NO but I dont know for a fact I have never used it to see...

I have glued many pearls to fondant cakes with buttercream icing. They can be knocked off, but you can re-stick it easy enough!

About how much buttercream must i put? i take it that it must be a very small amount
thank you,

If you HAVE to use butter cream
I would do what Ladycake said:

Just using buttercream instead.

Be aware that buttercream is not the best solution.

I've glued strands of fondant pearls to a fondant cake simply by wetting the area with some water. I use a fine water color brush to do it. The water will soften the fondant just enough to get sticky and stick together. Anther great option is the royal icing, but I would stay away from the buttercream.

If the pearls are dry and hard, water might not work. I use a small dot of royal to attach.

I have learned through my fondant decoration books that they're supposed to be glued with royal icing.
