On a scale of one to ten (one being the best and ten the being worst), seam ripping to correct a wonky stitch or to correct the fitting of a work-in-progress gets an off-the-scale one million rating, as per annoying things that can happen while I’m sewing. I literally gnash my teeth in agony as I unravel stitch by stitch.
Ah! my heart melted with immeasurable joy *insert delicious drips of sarcasm* the day I had to detach an invisible zip, when the zipper slider came off completely TWO minutes after I had attached said zip.
So, in instances when I have to draft a pattern from scratch and I am not entirely sure what the finished work will look like, and I have only a limited amount of the desired fabric or if I am using expensive fabric, I prefer to err on the side of caution by first sewing a muslin (calico test garment) which is also called a toile, to sort of “test drive” the pattern.
Above is the muslin and below is the final reproduction in the fashion fabric. Please excuse the creases, I wasn’t quite done with fittings.
