In reply to jonathan shepherd:
not quite sure what you mean my "torn a pocket" is that broken the lining or torn the outer material but anyhow. If it's the outer material you could try tenacious tape or get a couple of test swatches of material and glue them on with seam grip/storm grip (same stuff different makes)
if it's the inside just get your needle and thread out as it doesn't need to look tidy so just sew a few stitches along the edges you need to join to reduce the chance of the edges fraying and then sew the hole closed.
