Is that just cork that your models are one? That looks awesome.
yep, glue cork to the base, add glue and some mixed gravel for some variety then prime and paint... using different colors of washes after the greys was something I saw online and makes a big difference.
it's my go to basing now for all my non-daemon armies

Looks great! I've been thinking my old marine & ork bases need re-working and this is something I will be mixing in there. I have LOTS of bases to do, particularly if I upgrade to 32 mm for faux Primaris. (No way am I retiring a full company of figures!)
