This 18-inch flexible curve is a drawing and patterning tool that helps DIYers trace curves with ease and efficiency. The flexible curve adjusts quickly from shape to shape, and it has a maximum bend so you can easily create a wide number of shapes and designs. When you trace each outer edge of the curve, you get a precise 1/2-inch width.
unique tool, wonderfully useful
This tool really does come in handy. I used it to add my 1/2 seam allowance to a pattern. It was very easy to use!!!
