Here's how to do it:
Paint wooden beads with acrylic craft paints and spray them with a clear acrylic sealer when dry.
Cut a 1.5" wide strip horizontally (so it will have some stretch) across the bottom of a white t-shirt. (You'll want to cut off the bottom hem of the tee first and then cut your strip. ) You'll end up with a big loop.
Center the first bead in the middle of the strip. Knot the fabric on each side to hold it in place.
Add the remaining beads to each side, knotting as you go.
Tie a simple double knot at the top to close it, and done!
Of course, we had to make one for little sister, too!
