1.Cut two pieces of fabric, each measuring 22 x 70 cm. Fold and press a 1 cm seam allowance to the wrong side on one long side of both pieces of fabric. 
2.Place the two pieces of fabric together, right sides facing. The two seam allowances pressed 1 cm to the wrong side should lie one on top of the other. Sew the other three sides together with 1 cm seam allowance. 
3.Turn to the right side and press. Sew seven rows of stitching through both layers to form 8 x 8.5 cm channels. If necessary, draw channels with a marker pen or tailor’s chalk. 
4.Fill 125g of grape seeds in each channel. Pin each opening and sew by hand using invisible stitches or machine edge stitch 0.3 cm from the edge.
