i have t molding on my cabinet, because i bought an empty cabinet and it already had t molding installed. i didn't use any on my control panel that i made though. i thought about using a router and roundover bit to make the edges look better, but i was afraid that it would be too much.. so what i did was get a 1/8" roundover bit for my dremmel and used the router attachment for it to round over the edges. it is such a small bit that it is a very subtle effect. there are no sharp edges/corners, but yet it isn't so round that it looks out of place. i need to sand the edges because the MDF i used has a very rough edge on it. i am going to build a different panel, so i'm not going to bother, but i did like the look of the tiny roundover bit. i'll try to take pics tomorrow...but right now the batteries are dead in my camera and i don't have any AA batteries lying around.
