Snowy icicles - how to



I will be needing to create these kind of icicles/snowy structures, but I’m trying to figure out the easiest way. Attempted to use polysnow plugin, but it doesn’t appear to allow me making something similar. I’m unable to create this sort of long icicles, It’s more for creating a snowy surfaces as I see.
Any clue what would be the easiest way? Would be nice to have some sort of control over it (thickness etc’)…
thank you
