Usually don't offer information, just take it, but i may have a worthy offering. To those of us with no seamsters in the friends and family circle, or to those with my means, or to those who would spend more on guns and ammo.... I cut jean legs in thirds, hot melt one end, pressing it down and together while still hot (cant hurt to use a lot), then trim "seam" with heavy duty scissors. Fill bag with whatever media, I like pea gravel or sand, as full as you can while still leaving enough room to cleanly seam the other end. Trim and your done. Or don't trim, its all good. Did six in 45 min. Hope you find this useful
