VlaanderenThank you DjaliRiot and chadnorth !
Over the years since initial startup Games-Workshop miniatures had a so-called scale creep. While earlier miniatures were around 25mm, they became 28mm heroic scale and now they're more or less becomming 32mm scale.
When collecting miniatures with intent to play, you sometimes have difficulties to fit the various scales into one regiment.
There are some very easy tricks to circumvent this: elevation. By adding some scenery under a smaller miniature you can trick the viewer into thinking all miniatures have the same scale. Just make sure all the eyes of the miniatures are on the same height.
Two cheap items from the DIY store are: stones and treebark. I have a walking trail nearby with gravel, and some treebark chips under my bushes in the garden (to prevent weeds from spreading too fast). That's a lifetime supply of free modeling scenery!
The advantage of treebark is that it's lightweight and easy to glue with white woodglue, pattex, and other lesser glues. Miniatures can be attached to the chips by pinning and a little glue. The chips also provide a nice layered effect to simulate soil layers.
Gravel/pebbels are more rigid and won't chip or get damaged. But they need a strong glue like TEC-7 to attach to the slottabases. Pinning won't be possible so the stones must be very clean for superglue, or you might use TEC-7 for the mini's too.
