Exquisite jewelry needn't be fashioned from gold or studded with diamonds, rubies, or other precious stones. You can craft beautiful pieces with far more common materials, such as abalone-shell or pink mother-of-pearl buttons.

Abalone-shell or pink mother-of-pearl buttons
Beading string, cut to 40 inches
Fold the string in half, and create an end by tying two slipknots 2 inches down from the fold.
Slip a button on one string. Tie another slipknot 1 inch from the previous knot. Repeat until you have 12 buttons on the string. (Sophie makes five strands for her necklace, but you can make as many or few as you like.) Trim the ends (not the looped end) 2 inches from the last knot.
Gather all the ends together, and crimp in a crimp bead. Attach the necklace closure using a pair of needle-nose pliers.
