Before basing, it is really beneficial to paint the metal bases of the figures to match the eventual colour of the base; saves time and reduces the probability of needing to repaint the feet.
I make the bases in big batches and will cover this in another post, later; they are magnetic on the underside, and sealed with spraypaint on the top and sides.
So above, we have the basing mix; roughly 1/3 wood glue, 1/3 water and 1/3 dry mix as per the last post. Stir it up with the palette knife, then apply to the base, as below. Can anyone guess why there is an arrow, cut into the square base with the archers on?
Finally, it is essential to let the base dry on a magnetic surface (as below); or it will warp! I use an old baking tray. Make sure that the surface and the underside of the base are clean.
