Give a tired chair fresh style with a sweet and simple felted cover.
Cut felted wool sweater pieces into 5-inch-wide strips of varying lengths. Using a sewing machine, sew pieces in a patchwork design. Add various hand stitches, such as whip and blanket, for a decorative effect if desired. Continue to add pieces until the patchwork is large enough to cover the chair.
Cut a series of 12 circles from white felt, making each ¼-inch smaller than the previous. (Our largest circle was 15 inches.) Cut petal shapes in toward the center of each circle, with deeper cuts on the larger circles. Add color to the smallest six pieces by needle-punching yellow wool roving to the circle centers, adding more color as the circles get smaller. Layer the circles from largest to smallest. Tack the circles together in the center to puff out the petals. Sew the center of the flower onto one corner of the chair back.
Cut leaf and stem shapes from the green felt. With a running stitch, sew the pieces to the cover with the stem extending from the flower.
Remove the arms if possible. Place the cover over the chair and stretch around the frame. The patchwork will change size and shape as you stretch. Staple the cover underneath the seat and around the back. Finish the back by whipstitching each side closed.
