I am learning so much from these patterns, and now I have another question. I'm currently blind-stitching my bucket hat, and I was wondering why the pattern calls for it, when I'm to edgestitch the same part of it in the next step. Is it to make it more secure? I imagine that it makes it easier to edgestitch without stretching the fabric and having bunching at the end. I'm just trying to increase my sewing knowledge here :)
