   Just got some of the parchment to try, feels great.  Inside of roll is 
slightly more textured than the outside, inside being what's normally going to 
get cooked on the way the roll dispenses.  $2.24 with the Kroger card discount, 
the unopened $14 high temp silicone is going back if this works well at all. 
Still working on direct printing this weekend, but have to have something else 
as a good backup anyway.  I will be doing a couple boards tonight, so will of 
course report on how it goes in a while.

   Since I do a lot of shipping, if it works well I'll be willing to send it 
out.  If it's great I'll just tack $1 on to make it worth going to the store, 
and send it at that $1 over cost.  Should be less than $10 the slow way to 
almost anywhere including the cost, it's only $2.24 on sale or $2.99 when not.

   Apparently though it is 'the stuff' for high class non-stick baking though, 
you should be able to find it or something similar just about anywhere at low cost.



   And for alignment, if they can glue teflon down, there's a way to get 2 
sheets together.  May take a bit of trying but no doubt it'll work somehow.  You 
can always do purely mechanical.  Align, punch X shaped cuts, and fold through. 
  Enough of those will hold just about anything in alignment good enough for a pass.

   Need to finish my relayout of my current board to give it a try, but I may 
just have to find something else to make a quickie spare board of to see it work.
