Homebrew PCBs

I was messing around with all these old blue sheets.
Then I thought about others that wanted to silk-screen the component side of
the board. So I took the old Blue sheet and ironed on the finished component
side.
Sure enough it sticks better on the bare PCB than on copper and has a nice
blue lettering. I used scotch bright on it and it doesn't come off just
lightened up.
It didn't stick where there were holes, so you need to put it on before you
drill.
I'd have to say blue sheets work great as a cheap silk screen.
