Missouri RiverMountain Man's Workshirt Pattern

The directions contained with the pattern are terrible. The directions are very vague and in some steps you must figure out where and how things go together. I am new to sewing and could not figure it out. I had to have my mother who has been sewing for 55 plus years and she had issues understanding the pattern and assembly. We did make 2 shirts which came out fine but if you are new to sewing find a better explained pattern to make a shirt from.
