How To Alter Sewing Patterns
How to Make a Paper Sewing Pattern
Sewing Vintage: Three Essential Alterations for Vintage Patterns - This tutorial focuses on 40's and 50's patterns but has tips which can be useful for other eras as well. I believe the author is Gertie. She also gives one or two tips for updating a vintage pattern.
I like this article on It's Sew Karren's site, which "How to Take Sewing Measurements and Pattern Fitting Measurements." It includes a conversion table for fabric measurements and a simple description of the measurements needed to determine your correct pattern size, whether contemporary or vintage.
"Drafting Patterns for Women's Pants" is a tutorial on Leena's website. This site's tuturorials are for use with PatternMaker Drafting Software but some of the instructions and tips are applicable to hand drafting.
