Finally! The perfect ice cream texuture. This success has to be credited to Renee :) for the sandpaper tip.
I initially thought that patting the sandpaper was supposed to give it the desired texture but turns out that rubbing the sandpaper did the trick.
I am not sure if I would be able to pull of this technique in dollhouse scale but would get to some experimenting soon. I would also be making a cone for this one and turn it into a magnet perhaps. Photos of the completed product to follow!
