HOW TO DO IT: SCRATCHBUILD SANDBAGS
1 Use an old piece of wood as a flat base to create a guide. Then draw two horizontal lines (5mm apart) and then another two parallel lines (8mm apart). Divide the latter at 10mm intervals. 3 Press a thin piece of metal (upturned scalpel blade will do) into the clay at 10mm intervals - using the guide for reference. I tend not to cut all the way through when representing a long line of sandbags, for ease and stability. 5 Position the sandbags on your layout while they are still moist so that you can curve and position them accordingly. Once satisfied, leave to dry fully. 2 Roll a small lump of DAS clay into a sausage that fits snugly between the 5mm guidelines. Now place the sausage on to the 8mm guidelines and evenly push it down so that it spreads to fit. 4 Frequently brush the clay with water to prevent it from hardening. Repeat step three and build a wall to your desired height. Cut through the clay to create individual sandbags, and place where necessary. 6 Finally, paint and weather your sandbags. Although originally straw coloured, sandbags would often darken when exposed to rain or mud - something you may wish to reflect.
