True Bias Lander Pant and Short
Buy the Lander Pant and Short pattern with its beautiful high waist and button fly to push your skills (next on my sewing table). The Lander has all the classic features of a jeans pattern with patch pockets and belt loops with a straight cut leg.
With two versions to try out both full length and shorts length this is a pattern that is utilised for every season.
For fabrics, think denim for a classic look, twill for a really luxury feel, medium to heavy cotton or linen for summer versions for both full length or shorts.
