So I've been trying to get going on my stuff and get a vow in, but I'm actually stuck on a basing scheme. Anyone have any ideas for a "webway" base? My thought on the Lugganath army I'm building is that it will have Lugganath, a Harlequin troupe, and possibly some corsairs, all "emerging from the webway".
Have you considered trying a mist or wispy fog effect? Teased cotton, pillow filler, dental floss, or spider web (like the the kits you see in stores around Halloweeen time) will give varying densities.
