I'm not 100% certain what you're asking sorry. I'll just detail the whole thing.
Basically I've tried two methods thus far
a) (method done on my skull shrine piece)
-place white glue on base
-apply dried herb mix, shake off excess and wait to dry
-apply a thin mix of white glue, water and brown paint all over to seal it down and shade it.
-superglue completed miniatures / plants / flocking whatever on top, but don't paint it
b) (method done here)
-superglue model's feet to small rocks, and the rocks to the base
-white glue to the rest of the base
-apply herb mix, shake off excess, dry
-apply thin mix of white glue / water, dry
- prime and paint entire thing
The problem with doing it the B way is you lose all the color variety that the basing material already has and its near impossible to correct that after priming the whole thing because the base is firm enough it wont fall apart on its own but not nearly firm enough to stand up to direct pressures. The downside of the A way is you need to do the bases and models separately and only combine them at the very end which is a bit more work and I'm just waiting for the day I mess up removing a completely painted mini from its unpainted base with a knife to base it and I slice the mini's foot in half.
I'm open to alternative ideas on how to base, but I do like the "jungle undergrowth" look that basing with dried herbs gives.
