Skill level: Beginner. All seam allowances are 1.5cm unless otherwise stated. Suggested Fabrics: Oilskin, dry oilskin, mid-heavy weight cotton canvas or drill, mid weight denim (8-14oz). You will need: Leather Strap Version: Matching thread 8 x 9mm rivets 4 x 1″ metal sliders 2 x 1″ leather strap 89cm long When inserting the rivets we recommend using a very solid surface like a cement floor so there is no movement.
