Sweater Measurements Schematic

[yarnrainbow]

I am getting ready to make a sweater for my mom, who lives quite a distance from me, as I haven't been able to see her in person for several years. I think that her wrapping up in a sweater I knit with love will be the closest I'll get to hugging her before she passes. However, the distance makes fitting it to her in person impossible. Mom lives with my brother and SIL and my SIL has offered to take Mom's measurements for me if I send her a schematic that shows what measurements are needed and how to take them. I am new to sweater knitting and was wondering if anyone has a schematic for the usually required measurements that they would recommend/be willing to share? I'm hoping some experienced sweater-knitters have something at hand and I don't have to re-invent the wheel. Any help appreciated!
