If it’s any consolation… I co-owned a costume shop for 42 years, where most of my job was spent making patterns and cutting. Next to setting sleeves in a suit coat, two of the hardest things to sew are zipper flys, and welted pockets… both of which I’d get rusty at, and have to rethink through the sewing steps when I’d have to sew. 
The only bad questions are the ones not asked.
