  USING THE TEXTURE LAYERS
  This model includes PDF files with multiple layers that you can make 
  visible or invisible. To adjust the layers, open up one of the PDFs, then 
  open the Layers menu. Expand the Layers Palette to reveal the selection. 
  Some of the layers will be visible to start off with; most will be invisible. 
  Click on the ‘eye’ icon to change a layer’s visibility.
   
  By choosing differen combinations of textures, you can create a 
  unique look for your model. When you’re happy with your design, just 
  print it off.
  PRINTING TIPS
  These PDF files are set up for the standard 28mm-30mm tabletop 
  wargaming scale, and for US letter-sized (8.5” x 11”) sheets. Turn off any 
  ‘fit to page’ options in your printer driver. If you are printing on A4-sized 
  sheets, you may want to reduce the print size to 95% of the original.
  GLUE AND PAPER TIPS
  To get the best results, experiment with different papers and glues, and 
  take advantage of whatever printing methods you have available. I prefer 
  laser color copies printed on 80# or 110# (199 gsm) matte cardstock.
   
  The best choice of paper and glue will depend a lot on the printing 
  method that you choose. I use a low-moisture, tacky glue. Small dabs of 
  ordinary white school glue usually does the trick, but for covering large 
  areas I like to use a glue stick.
   
  When applying glue, a thin and even coat is much better than a 
  heavy glob. I cut up excess cardstock into little squares, and keep these 
  handy so that I can spread out glue onto tabs. It’s a good idea to keep 
  some slightly-damp tissue if you need to wipe up extra glue, but be careful 
  about this is if you’re using ink-based prints.
  MODEL ASSEMBLY BASICS
  Using scissors or a hobby knife, carefully cut along the outer black lines of 
  each piece. Using a hobby knife, carefully score along each of the remain-
  ing lines. (To score a line, lightly drag the tip of your hobby knife.) After 
  scoring, lightly fold back along each of these scored lines. Note that some 
  sections may be folded forward instead.
