This was posted over at MRH forum. It's so good, I wanted to share it here:
Small pine trees are very common (at least in the northeast US) at the edges of woods, along roads, cuts, etc. Mix them up with tall weeds and shrubs.
Now "Barbatos Rex" on YouTube talks about using a food dehydrator to speed drying time on paints. That would probably also work for speeding up the assembly time for these trees.
