I know many doll house enthusiasts use mini wallpaper, but have any of
you completed miniature murals/paintings or tromploei in a doll house
setting? If you have would you post photos of your work & /or provide
any tips?

The only tip I can offer, and this can apply equally well to paint or
paper, is to do your painting or papering on separate insertable wall
covers (thin cardboard, for example) to avoid having to work with
12-inch hands in a 1-inch (or half-inch or quarter-inch) setting!
