Hey!
I’ve run into Problems with the Simon pattern. I chose to do the Button placket with the Same fabric as the rest of the shirt, so I included it when cutting the fabric. Now as I’m following the instructions to finish the shirt the whole left chestpiece is too wide and won’t fit into the collar.
When starting at the middle of the yoke and the middle of the collar the right side fits just fine, but the left side is about 3,5cm too wide. What am I doing wrong?
