TheWalbrook Boxer Briefs are a fun project for anyone! Choose fabrics with at least 50% stretch and some lycra or spandex for good recovery. There are options for a functioning fly, a non-functioning fly, an encased elastic waistband or an exposed elastic waistband, and two different lengths. There is even a special optional technique included in the instructions for those who love to build their skills! The pattern includes sizes S to XXXL or waist measurements of 28" up to 50". You will need 3/4 yards of 55" - 60" knit fabrics.
