Create a paper pattern by cutting out a circle with a 2 5/8-inch diameter and a rectangle that is 1 1/2-inches x 8 3/4-inches. Draw 7 triangular sections inside the circle and cut one triangle out of paper.
Cut two circles, one rectangle and seven triangles with a sharp pair of scissors. Sew a small white button to the center of the top felt circle.
Using a straight stitch sew the triangular sections around the button on the top circle piece. Sew the trim to one of the long sides of the rectangular piece of felt.
Place the circle and the rectangular pieces of felt with the wrong sides together, and attach the two pieces along the top edge. When you get around the entire top edge, overlap the short ends of the rectangular piece and use a straight stitch to attach them together.
Now attach the bottom circle piece with a blanket stitch, leaving an inch open and pour the sand into the pincushion and close the opening. Now you can pin on.
