is considered a good sculpting medium and is used by many professional miniature sculptors. Green stuff is another two-part epoxy putty, with blue and yellow components that turn green when mixed together. Both Milliput and Greenstuff must be allowed several hours to dry (although this can be sped up using a hot lamp). Milliput is recommended for sculpting the frame of larger miniatures, as it dries hard and can be chiselled away with a knife afterwards if necessary. Greenstuff or 'Kneadatite', the putty sold in Games Workshop stores, is softer and much stickier than Milliput. When fully dry it retains a degree of rubbery flexibility. Although initially much harder to work with, Greenstuff is a superior medium to Milliput for sculpting small miniatures such as 25mm figures, and is widely used by artists in that scale. In addition to sculpting, modelling putty can also be used to cover up any gaps left when using other tools to convert miniatures. Types of conversion Repositioning and weapon swaps Repositioning body parts such as the head, arms or torso of a miniature figure is one of the simplest types of conversion. Another simple technique is weapon swapping. Weapons can be taken from sprues or other miniatures and used to replace whatever weapon the converted miniature is holding to create any variety of distinctive commanders. Conversions can also be used to give miniatures flags, banners or pennants if desired. A banner can be added to a miniature bearing a pike or spear, or a flagstaff can be made from a brass rod, which is quite rigid. In the latter case, any weapon the miniature is holding must be cut away and the fist drilled out to allow it hold the wire pole. The banner itself can be made from paper and painted with PVA glue, which stiffens sufficiently as it dries. The banner is then glued to the pole and painted. Head swaps Head swaps are a very easy way for wargamers to create unique miniatures. As the name suggests, the head of one miniature is substituted for that of another. The hobbyist must take considerable care when removing the existing head of the miniature to be converted, both for safety and to ensure the best surface to place the new head upon. Most of the head is clipped off and anything left is filed or shaved away with a sharp craft knife. This
