So, out comes the wood rasp . . .
And yet-another coat of goop . . .
And another - hopefully last - coat of .... not goop but paint!
I do like how the cardboard web/plaster cloth/ground goop combo creates random terrain undulations automatically, without having to be carved like foam (and with much less mess). But I have to say, this process isn't turning out not to be that much quicker - especially for relatively flat areas.
What would you have done differently here, if anything?
