Not knowing how much you want to build, I would start with 1 each of the 1" thick and 2" thick sheets. I bought 2 of the 2" ones and 1 of 1". I have more than half of a 2" sheet left and about half of the 1" sheet. If I was starting again from scratch I would add a second 2" layer to the base so it flexed less when moving it around. Also if you are going to build a tunnel, make sure you can access it. My whole mountain top comes right off. I refuse to build a derailment area i can't reach!!
