krystalina, I searched all over, went back to the source of my pattern and even found it somewhere else. BUT always these letters are missing.
I thought of being creative... if you dont find them...
Look, missing letters S T V
From letter I you can manage an S
From letter F you can manage a T
From letter w you can manage a V
You will have to play with the grid a little bit. Just an idea, for you like it so much!!!
