after i made one of these , i realized [sp] that its. just a regular bag with the metal tape measure [cut one inch shorter that the top , i call it the hem, inserted into it.and sew up the side seam. you can make the bag any size you want.oh, cover up your metal tape good , i found in my husbands stuff, some trasnparent duct tape, and used that to cover the tape on both sides, this tape is wide enough to do it, so the tape won't cut into the material, and you can see the numbers that you see when you put the tape into the right side of the hem. did i explain it good enough!!!!!
