Log-built walls and towers suitable for the Dark ages through to the Renaissance era made up of 9 printable sheets.
Once downloaded, the sheets can be printed as often as you like, which means you can build up large armies very cheaply. You will need scissors, a craft knife, glue, appropriate paper and some stiffer card for bases, all of which are described in the how-to section.
The figures are laid out on A4 format, which will print onto US legal sized paper, or will fit US letter size printed at 93%. You can, of course, print the figures in any scale you choose, making them uniquely flexible in this respect.
You will need to make a stiff 40mm wide card base for each stand. It should be 30mm deep for three rank infantry and all cavalry, and 20mm deep for two rank infantry and skirmishers.
