/cgl/ - Cosplay & EGL

Main goal:
>be more punctual
In high school I was on time or early to everything both school and family related. Now in college I'm sometimes late to my first early morning classes and always late to family events. I know for school I just need to wake up earlier but for family events it's a bit hard since I'm usually waiting for my boyfriend to finish getting ready.

>understand the science of sewing
I took 3 years of sewing classes in high school and continue to do little projects so I know the basics. What I want to learn is WHY certain pieces work better than others, what darts do, how the curve of an armhole effects the garment, etc. Someone recommended this book to me and I was wondering if anyone could confirm or suggest something that has helped.
