Journal editor Roger Walter requested permission to use my design, as his “From the Editor” column in the current issue is largely about curve stitching.
I suspect that most readers have no idea what a vinculum is, by the way. I certainly didn’t when I received my first e-mail message from Roger. (Dictionary.com notes that “[f]ew English speakers likely know this word.”) A vinculum can be a bond or tie. In mathematical notation, it is a horizontal line used to group expressions in some way. The horizontal line in a fraction, for example, is a vinculum. (See Wikipedia for more details.)
You can learn about curve stitching and see more of my curve-stitch designs on my Web site here.
