Slap bracelet is interesting, but I wanted a very simple apron that I could give to church members while using up some yardage of the toweling I have. As for safety -- I've been wearing the one my secret pal sent me several years ago while cooking indoors and out and I haven't gone up in flames yet. It sure is convenient for wiping up the blood after slicing meat with dangerous knives and polishing dangerous glasses that can break and cut you. Much more worried about slicing my fingers with a rotary cutter, sewing my fingers together, or being buried alive under an avalanche of fabric!
But we all have our own level of comfort and that's what makes the world go round -- not gravity!
