I did the same thing for a while, skipping any kind of fancy transfer
paper. I just photocopied it onto plastic transparencies, then ironed
them onto the boards. Sure, I had to go back with an etching pen and
fix 20% of the traces, but its all good fun at the end of the day. For
50 cents an 8x10 you can't beat the price! The only time I had trouble
was when someone left the photocopier set to 95% reduction and I
couldn't figure out why all the parts wouldn't fit in the holes.

My $1/50
