Hmm, we don't have any of those stores here in vermont.Or at least 
none close by. You would think that for such an expensive state to 
live in we would have more stuff to show for. Anyways, I'll see if 
they have anything close to that at staples and give it a try. Now, 
This morning I tried a small piece of left over PnP paper and it 
worked pretty good exept for a few smears because I press the iron 
too hard. I also tried another piece of photo printer paper but this 
time I did not soak it in water. I had better result without the 
water but I was still mising some sections of the drawing. 

   Again, I'll give the inkjet paper a try and hope it does well. I 
mean for the proce is really good. However, this morning I tried a 
pice of lestover PnP paper and besides minor smear in one section it 
transfered really good. What I'm saying is that if its a lot of work 
to transfer the traces using other papers then I'll just stick to the 
PnP. I mean is expensive but if it works?!! However, I won't give up 
on other papers becuase the price and availability are just too good 
to ignore.
