When a customer requested a custom knit sweater vest with a round neck I quickly found out why it had to be custom-made as well as custom designed. It is surprisingly difficult to find a vest without a v neckline in ready-to-wear or even in a knitting pattern. There were a few measurements that I felt were critical to fit. I had my customer email me the finished width (1/2 circumference) of the vest as well as the desired length and finished width at shoulders. I usually suggest that if they have a sweater that fits well this is the most reliable way to get out new one to feel…
