This top was made using Simplicity 1619. The pattern was fairly easy. I think the toughest part was the manipulating the fabric. It was somewhere between gauze and linen. I am sure there is a more exact name but I haven’t a clue what it is. Anyway, there were a number of problems; such as fraying and slipping. Ultimately, it came out great but I will think again before using that type of fabric for a pattern like this.
