In the US, Miniart supply various brushes suitable for miniaturists. For lifting off paint from a non-absorbent surface the nylon Daler size 00000 made by Dalon is invaluable. Even the best nylon brushes bend at the tip after a certain amount of use, so aim to buy natural bristle brushes if at all possible - they are worth the extra cost. The generally accepted maximum size for a miniature in the UK is 4.6 inches x 6 inches including mount and frame. The Royal Miniature Society does not accept mounts wider than 0.75 inches.
Frames are usually custom made with very fine mouldings.
Oval, circular, rectangular or square gold or brass plated frames with convex glass are also very popular. Suppliers include RJ Wood and Polymers Plus in the UK, and Miniart in the US . Beautiful and unusual frames can also be ordered from Haffke Kunsthandwerk in Germany. All but the very youngest will require some help with seeing the very fine details of a true miniature. In the UK any good optician will have a range of magnifiers.
