6 Felt circles - The circles I used are 4 1/2 inches in diameter. I do not recommend using anything smaller than 4 inches.
Ribbon 3 inches in length
Line up all six circles on top of each other. Fold ribbon in half and place in the center of the circles (three in front & three in back). Stitch down the center sewing the ribbon to the felt and at the same time sewing all six felt circles together. Refer to picture.
From a top view the ribbon should look like this. In this picture I only have two circles on each side. Your ornament should have three on each side.
Pull the edges of the first circle together. Stitch in place where you see the white circle in the picture. Make sure to conceal your knots in the inside. Click on picture for a larger view.
Pull the next circle flap on the left hand side up to the center. Stitch together where you see the white circles in the picture. This will be the pattern for the entire sphere.
Pull the next circle flap from the left hand side and stitch to the center of the last flap. Stitch where you see the white circle. Continue with this pattern(one center stitch, two top and bottom stitches) until you've created a sphere and every circle flap is attached to each other. Done.
