"My 1" test square measures smaller. How can I fix this?"
Please always ensure that the 1" test square on your pattern piece measures 1" EXACTLY.
To print accurately, please take note of the following guidelines:
1) Do NOT print pattern from your phone/ipad.
2) Print from a laptop/computer.
3) Open the file with Adobe Reader (not from browser preview).
4) Select A4 for paper size.
5) Select 100% or Actual Size.
I hope this helps!
