If you love to rock climb or know someone who does this DIY chalk bag might be the perfect gift for them. The little bag is mean to hold chalk which climbers use to give their hands more grip on the rock. The bag is worn around the waist where the climber can easily get to it while climbing.
This is a bag you can sew from canvas or a heavy cotton fabric. Vinyl might work too as would just about any fabric that can withstand abrasion.
