The next stitch in Sharonb's Take a Stitch Tuesday is the Buttonhole Wheel Cup. It makes nice texture. On the light blue I added two rows of stitches around the wheel. It and the green are Perle Cotton. The dark blue is wool.
The last bracelet for Christen Brown's class at http://www.joggles.com/ is made from clear button and uses the dark beads that are irridescent and change from blue to green to purple.
