Most of the vines consist of the “trash” sprue that comes on this part.
If you have the part you know what I mean. There is a sort of triangle ring that holds all 3 leaves together and protects them from bending or breaking quite as much until you build with it. I’ve kept mine for years but never really knew what to do with them until now.
This may not be the first person to do it, but I’ve never seen it before and I like finding new ways to use old parts.
The whole set of pictures has some really great building techniques in them and I recommend reading the story as well.
