Grab Mom around the wrist the next time you're talking to her. This should give you an approximate measurement of her wrist.
16 gauge silver wire
24 gauge silver wire
small wire cutter
small needle nose pliers
steel bench block
Pound the wire pieces flat with a hammer on a piece of steel. A concrete garage floor will work in a pinch. This will make the wire stronger and more jewelry-like.
Place the "O" in the middle of your wire loop. The opening of the "O" should be opposite the loop opening. Cut short lengths of the 24 gauge wire and wrap them around the letters and the bracelet where they meet. I wrap just a few times just to hold them in place then finish wrapping when all of the letters are attached. Wrap wire between the "O" and the "M"curlicues to attach them together. Lastly, wrap the short wire where the "O" meets the split in the loop. By this time the bracelet will be stiff enough to make this wrap a little easier. Cut the ends off of the 24 gauge wire on the outside of the bracelet. Tuck and file if necessary. No sharp ends please. Lightly tap the small wire joints with a hammer to set them.
