From Angela Kane:
Make Your Own Jeans - this is the perfect jeans pattern for selvedge denim. The outside leg is cut along the grain so that you can utilise the attractive selvedge edge. If you are not using selvedge denim, this sewing pattern makes up just as well in classic denims.
Selvedge Denim
Selvedge denim is characterised by its firm, often striped and always neat selvedge. It is woven on traditional hand looms and is narrow compared to modern denim yardage.
The pattern uses this lovely finish on the outside seam which is on show when the cuff is rolled up. The pattern is special to selvedge denim as the outside seam is straight from cuff to waistband. You can though make this up in a non-stretch denim - it's a great pattern.
