Place tracing paper over the pattern at right and trace it using the iron-on transfer pen. Center the traced pattern, ink side down, on the linen square and transfer according to the manufacturer's instructions.
Place the fabric in an embroidery hoop and embroider the design with split stitches and one strand of wool thread. Note: For embroidery-stitch instructions, see link above.
To block the finished piece, use a damp pressing cloth and steam-press it on both sides.
Frame the stitched piece or sew it into an ornament as follows:
Trim the piece 1/2 inch beyond the embroidered design.
Cut a matching shape from backing fabric. Fold a 9-inch length of ribbon in half and sew the ends to the top of the stitched piece.
With right sides together, sew the ornament front to the backing with a 1/2-inch seam allowance, leaving an opening along the bottom for turning.
Trim the seams, turn right side out, and stuff. Sew the opening closed.
