Itty Bitty correction:

After a pattern has been proof read it is corrected and saved. The old one is deleted and the new file goes to the printer. Guess I am showing my age. I deleted the proof read file and sent the original file to the printer. I’m so sorry if this has caused you trouble. Follow the instructions below to make the corrections.

Group 1 patterns - Upper right pattern Count from the upper right corner square of the pattern down 6 squares then left 9 squares and delete that symbol.
Group 2 patterns - Lower right pattern Count from the center square on the right side edge up 2 squares then left 5 squares - add 1 square symbol that is missing. 
Group 3 patterns - Upper left pattern Count from the lower left corner square up 14 squares then right 15 squares and delete this symbol. 
Group 3 patterns - Upper right pattern Count from the lower center symbol up 6 squares then left 3 squares to delete this one symbol. 
Group 3 patterns - Lower Left pattern Count from the lower right corner square up 2 squares then left 8 squares to delete this one symbol. 
Group 3 patterns - Lower right pattern Count from the upper right corner down 2 squares then right 4 squares and delete this symbol also delete the symbol directly below it. Count from lower right corner square up 10 squares then left 3 to delete symbol. Also delete the symbol directly above it.
