Joe, the whole tunnel project came out beautifully. I can understand moving on now and leaving vegetation and detailing to a later time once the major projects are done. I love how you recycled construction plans for your drop cloth.
We used to print up so many sets when we would put out a job for bid we always wound up with extras. I used them to wrap Christmas presents.
I never would have thought about stacking the foam instead vertically instead of horizontally. I think yours was a more efficient way of forming the mountain.
