Purchasing new wool fabric can be quite expensive, but recycling those old wool knit sweaters can provide you with an affordable source of wool. Dig through your closets for torn, moth eaten or outgrown wool sweaters to make beautiful wool sofa cushions. Wool is a wonderful fabric to craft with, as its edges do not ravel or fray. Simple topstitching can be used to applique shapes easily, making the construction of appliqued wool sofa cushions a quick project.
Wash two adult wool sweaters of coordinating colours in hot water and dry in a hot dryer. The agitation of the cycles and the heat will shrink and felt the knit of the sweaters to create a solid fabric. Cut the sweaters apart at the seams and lay the pieces flat. For ease of instruction, one sweater will be sweater A and the other will be sweater B.
Measure and cut one 15-inch square from sweater A. This is the back of the wool sofa cushion. Measure and cut two 8-inch squares from sweater A and two 8-inch squares from sweater B. These squares will make up the front of the wool sofa cushion. Lay a 4-inch wood heart on sweater A and trace around it twice using tailor's chalk. Cut out the two hearts. Lay the 4-inch wood heart on sweater B and trace around it twice using tailor's chalk. Cut out the two hearts.
Lay the four 8-inch squares on your work surface. Center the A hearts on the B squares and the B hearts on the A squares. Pin the hearts to the squares. Topstitch the hearts to the squares a 1/4-inch from the heart edges.
Lay the 8-inch squares on your work table and position them two across and two down in a checkerboard pattern. Place the top two squares together with the heart sides facing and the hearts pointing in the same direction. Pin the squares together on one side edge. Sew the pinned edge using a 1/2-inch seam allowance. Repeat for the other two squares. Note: Stack and sew the exact same side edge with the opposite square colour on top.
Unfold each square pair and iron the seams open using a wool setting on your iron. Position the squares in the same checkerboard pattern. Fold the top row over the bottom row with the heart sides together. Match the centre top seam and pin the top edge. Sew a 1/2-inch seam allowance along the top edge. Unfold the squares and iron the seams open. This is your wool sofa cushion front.
Lay the 15-inch wool sofa cushion back on your work surface. There is no right or wrong side to this piece. Place the cushion front right side down on the cushion back. The side with the hearts is the right side. Match and pin the edges together. Sew around the cushion edges using a 1/2-inch seam allowance. Leave a 4-inch opening along the bottom edge for turning.
Clip the corners off of the cushion cover. Turn the cushion cover right side out. Fill the pillow with stuffing. Pin the opening closed. Hand sew the opening closed using a hand needle and thread.
