Quadra Jeans

 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 flatfell 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 center 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.
