You know what's heartbreaking? Hand-sewing about 55% of a pair of trousers, including side seam pockets, and then realizing that they are about 4" too large for their intended wearer in all areas except the waist. Carpenter jeans: not a good Regency look.
Actually it was more super-annoying than heartbreaking, because taking out backstitch without a seam ripper (I can never find one when I want one) is a whole lot slower than ripping out machine stitching. Ah well...they should fit now. Once I finally put them back together, that is.
