Special cut-out flagstone-style bases for cardboard minis are now available to download in a zip pack on the Onebookshelf sites http://bit.ly/IAbases - Ideal for use with minis on sections from the Modular Cut-Up Dungeons Basic Pack.
These are by no means a definitive choice of base for paper modellers. In some forthcoming packs ("Encounter-Lair" working title) which include cardboard miniatures, different styles and assemblage may be included in the range.
Thanks for browsing. Bb. :)
