Step 4: Sew the Fabric on
Get a long length of thread on your needle and tie a few overhand knots at the end. Sew around the edge of the rock so that the only part unsewed is the very top with the string sticking out. Then use the string and go through the knot many times so that it is secure. Keep doing this until it is secure. Then sew up the rest and tie off the thread and cut it.
