Buy the Men’s Quadra Jeans sewing pattern from Thread Theory. The Quadra Jeans sewing pattern provides a subtly modern take on the classic straight leg jean. This pair of jeans features a slight taper to the leg and extra room in the thigh to allow for lots of movement. They sit below the waist as a moderate low rise. Sew these jeans in denim with no stretch or up to 2% elastane to add just that little bit of additional flexibility that so perfectly suits an active lifestyle.

This jeans pattern features all of the traditional details required when sewing denim – add lots of strengthening topstitching, learn to sew flat fell inseams, construct a zipper fly, and apply rivets to high stress areas.  As an added bonus, the waistband is drafted in two pieces with a centre back seam hidden under the belt loop. This construction style allows for very easy fit modifications, even once the jeans are fully constructed. This is a perfect solution for the home sewist who might like to sew these as a surprise gift or for the wearer with a fluctuating waistline.
