Unshrinking wool fabric?

[SO_tailor]

Hi there!

Is there a way to Un shrink wool fabric? I was trying to shape the coats' back with the iron, but ended up shrinking the half back by a 1/4". I read a little and found that wool sweaters can Un shrink in hot water, but didn't know if this worked on fabric.

P.S. I have no usable inlay in the center back seam (cut on the selvedge), so I can't do anything there to widen it.

I would rip the seams. So the fabric can relax. Then wet the fabric roll it together and let it rest. After resting pin it in the real size on a blanket. Be careful with the grain. Let out steam from above and soak the fabric evenly. Take a fine cotton fabric piece, lay it over the your fabric and press with a dry iron. Don't pull. Just press. Let it  cool. This should work.

That's a great description, thank you posaune.

Yes, thank you, Ma'am.

A similar process works for knit wool but adds salt to help fill the fiber 'ridges' and holds them away from each other during drying. Warm, salty water, stretch t' shape and pin, let dry slowly. Rinse in fresh cold water. Usually works but wouldn't at all use salt on suitings for staining likelihood. Just adding to round out topic.
