Thread Theory Men's Quadra Jeans

Buy the Men's Quadra Jeans sewing pattern from Thread Theory. Quadra is a subtly modern take on the classic straight leg jean, with 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 that little bit of flexibility for 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.

Suggested fabrics:

Self fabric: Denim fabric (9 - 16 oz.) or bottom-weight fabrics such as twill or corduroy. Fabrics with no stretch or up to 2% elastane (spandex) are suitable. A higher elastane content will change the fit and it may be necessary to size down. Ensure your sewing machine can handle the denim weight you choose by sewing through five layers of the fabric.

Pocket lining: Pocketing, broadcloth or other strong cottons or cotton blends. This is a great opportunity to use novelty printed cottons as it will only be visible from the inside of the jeans!
