Well i'm probably guilty of most errors here ;o) but one thing that does bug me is scale, like when i see a chair thats to big or too small, get the tape measures out folks and measure the stuff you have in the house, stand next to things or in doorways and get a feel for how wide they are and tall compared to you....then use these as guides to how big your objects should be....my 2 pence ;o)..Steve
