The inside blind-stitch is suitable for any fabric but is particularly good for hemming fabrics where an inconspicuous hem is difficult to achieve, such as knits and wool flannel. Fold the hem edge back about 6 mm (¼"). Take a small stitch in the garment, about 6 mm (¼"); take the the next stitch 6 mm (¼") ahead in the hem. Continue, alternating stitches between the hem and garment.
