I need to make trees for my layout, mostly oak and elm, and I want to model spring, so the foliage isn't too dense. I can't really buy anything right now, so I'm looking for alternatives. As autumn is descending on Sweden, most weeds I might be able to use are gone. I had hoped I could spend the winter making some trees, but started to look for materials too late in the year it seems. Tiny tree saplings might give nice roots for making the tree branches, except the ones I found didn't have the right profile for the trees I want to make. I have some dense foam I'll turn into scatter, and some felt in different colours that might work as well. I'll have enough for experimentation. I need some ideas for the trees, what have others used to make trees from scratch? I know about the way to turn a wire into a tree by dividing the strands into thicker and thinner branches.
