Personally, I’d say no flocking. Just another thing to set up and clean up and we lose the ability to summarize the display as “only lego parts” (aside from the stickers).
I concur.
And, Greg, stop making me feel like a n00b by making awesome MOC after awesome MOC! I’m gonna be lucky to have a halfway decent pile of rocks, and you just built a GBC on top of all your other contributions…
