You will need:
Cut out a long strip of felt. Measure it out in to squares (I used 2" squares) and cut out six squares.
Tack two of the squares together with a matching colour of thread.
Sew the two together using a hemming stitch.
Sew another square along the side on one of the squares.
Sew another on to another side of the same square.
And another on the remaining side making the shape above.
Sew two of the sides together turning the shape 3D.
Sew another side together and then sew the final square on to the top of the shape.
Sew together another side leaving only two sides/one corner unsewn. Fill the shape with foam and then sew the remaining sides.
You will have now made a cube. Take your dots (there should be 21) and glue them to the cube.
Make sure that your opposite sides add up to 7. And voila, you have made a dice.
Repeat the first steps and make another dice.
Using the yarn needle sew a piece of wool between each of the dice.
