Why You Must Pre-Shrink Hair Canvas

Once, after I dry cleaned a wool coat that I had tailored by hand, it was returned with bumps, waves, and ridges. While the wool fashion fabric didn't shrink, the hair-canvas did, causing great inner conflict in both the coat, and in me. I didn’t know that the materials used inside the coat were supposed to be pre-shrunk as well. This was a difficult lesson to learn.
