Using a T-shirt which I really like the fit, figured out where I needed to take in the edges and bottom. They are labeled as the same size (Large)!! #sewing

Marked the edges with chalk. Note:I probably should have ironed them both first, I had to rip and readadjust the seams because these markings were slightly too tight. #sewing

There was nearly an inch difference... again, same label size "L" #sewing

Quick run through the old sewing machine (not shown), and I had to adjust it a bit, but there we go .. (I prefer a slightly tighter fit on the shirt, but that definitely is a negative as middle-age gut expansion occurs lol.) Before adjustment it was too far into "muscle shirt" territory lol. #sewing
