I've seen a few adaptations of this cake so I'm assuming these flowers were made from a mold? If so, does anyone know which ones? If not a mold, could they have been hand cut from fondant/gumpaste?

Also- I can't seem to find who made the cake...no bakeries have been credited? Does anyone know?

Thank you!

I think it is various flower and leaf cutters of different shapes. they will be placed on the cake randomly but in a way so it all looks well placed, then royal icing is used to link them together and form a lace effect.

I agree.
 

Check Amy Beck Cake Designs.  There is a reference to the flowers being hand cut on ilikeweddings.com but I agree with others that cutters were used. Cheers

 Yes it looks like it's from Amy Beck Cake Design! She's an awesome cake designer. Thank you!

I can see a rose calyx cutter (I think), and a 5 petal rose cutter, hand cut leaves most likely, some other cutters, and probably some hand done texturing on some. Love that look.
