This is an effective way to develop your accuracy, with immediate feedback on how well you did!

Steps

  1. Get a reference image.
  2. Enlarge canvas to 200% width.
  3. Create a new layer and indicate placement marks on the reference image: top, bottom, left, right.
  4. On the empty side of the canvas, do your placement: top, bottom, left, right.
  5. Double-check the lines you’ve drawn. Move them, refine them, until they look perfect.
  6. When you’re ready to check, drag your placement lines on top of the reference image.
  7. Enable “Lock Transparency” on the placement line layer and color-code your lines. Green = nailed it, orange = close, red = off.
