I have a mass of Essex late Dark Age / early medieval 15mm DBA armies picked up in a 3 for 2 sale some years ago, and they seem like good candidates for a block paint and dip approach. Not to mention that with Dux Bellorum on the shelf it seems criminal not to try to get them tableworthy.
So here we are then. Block paint dullish colours.
Add acrylic stain. Used as-is, and applied with a wet brush.
Hmm. Not spectacular, but probably comparable to other more expensive products. With a highlight here and there and a coat of matt varnish these might look OK.
