Almost finished - just Stick to it!

• First, wash your hands to remove any dirt or oils you may have acquired so far. Then, find a secluded and well-ventilated spot in which to work.
• Lay one section of the background out on a clean and dry surface. Place the corresponding poster elemnts in position. Use a T-square and soft-lead pencil to lightly mark the positions of each corner of the poster elements.
  
• Put some scrap paper down on another surface to protect it, place a one of the poster elements face-down on the scrap paper, and apply adhesive. Place it in position on the background, then move to the next poster element and repeat. Clean your fingers often, to avoid sticky fingerprints on the poster - dust will stick & the prints will darken with time. Use absolute alcohol to dissolve & clean sticky spots, but be sure to test it in an inconspicuous spot first! Like the adhesives, some inks and paper dyes are soluble in alcohol.
  
• Keep going until you finish, changing the scrap paper often. Use a gum eraser to rub out any obvious pencil marks. Then lay out the entire poster again, stand back (about 15 feet), and look for errors and mis-aligned bits. Change any problems now, before the adhesive sets!
