While at a Michaels or HL store, in addition to paint, look over some of the other areas. In the beading area they have ultra fine wire, which is getting to be hard to find elsewhere. Small beads are nice for some detail such as knobs and lever handles. Felt sheets can be used for grass on bases and dioramas. They have some nice small tools, also. Don't know about HL, but Michaels carries airbrushes and airbrush parts.
