Many years ago I tried to make a plant out of it by cutting leaves into smaller shapes. It wasn't very convincing, but I was less demanding then. What I have now noticed with my trained eye was that the leaves were assembled individually and very easy to take apart.
I cut off a branch and stripped it of all large leaves. Then I took all small leaves from other branches and stuck them onto my branch. There are tiny pegs, and each pair of leaves has a hole.
I now had four branches with small leaves. Commercial dollhouse ivy you can get from ebay has leaves 1cm broad. So I am not too far off the mark. I also had to twist the leaves to make them all face in the same direction (which I guess is the opposite of the original).
To make it look natural, I attached every second or third leaf to the surface with sticky dots. In real life it is of course the stem that sticks, but it was easier so. I used two branches on top of each other. They are of course deliberately asymmetrical.
I think the house exterior is getting more interesting with each step. I will now try to make some hanging plants to put on the upper balcony. Come back soon.
PS I have conscientiously put all large leaves back on the remaining branches so that I can still use them for their initial purpose.
