Build a scaled model of the Eiffel Tower.
I’ve been thinking along similar lines - although I’m still working. With all the free weekends I have thanks to my local SCCA region either cancelling or postponing club racing events, I could get to work on building my next model railroad (I model in N scale, btw).
Bought a GP9 locomotive on eBay a couple weeks ago, and now I’m waiting for some Unitrack I bought off Amazon to arrive. In retrospect I should have ordered that from a US-based online retailer. The three different items I ordered all came from different Amazon sellers, and two of them are in Japan.
