Homebrew PCBs

hi,
hope some1 can help me with this.  i've been trying the old toner 
transfer method.  i've tried it with a couple of transparencies.  i 
think 1 from 3m one from a generic producer and some other. couldnt 
find the hp transparency.  some even had a rough surface on one side 
like i read in some post.  i tried with photocopied transparencies and 
with laser printed ones.  the printed ones were much sharper though.  

what happens is when i iron the transparency on the board it shrinks 
slightly and the design gets smudged. i i mean really smudged at some 
places.  i tried it with epson glossy paper too. same thing happened. 
when i ironed it the paper shrunk mostly from the middle section and 
the design got smudged beyond recognition.

i'm fairly new to this. and i need serious help.  what am i doing 
wrong?
