I don’t know if this counts as a ‘technique’ necessarily, but I don’t know where else to post it, it seems better here than the ‘ideas’ thread.
Specifically, I am posting this pic for the lime/medium azure/blue path made of 1×6 plates. The motivation for this is that at the Trolley Museum in June, I was part of a conversation with Laura and David where one of them (don’t remember) said they have a huge supply of 1×4 plates and they were trying to think of something good to use them all up. So I thought of that as soon as I saw this pic.
