Windows Border

The Windows Border is an easy two round pattern that can work with just about any pattern, but it is particularly suited when you’re bordering squares or blocks that have been joined by one of the “loopy” methods, where chain loops are made all the way around the square. This would include the Tight Braid Join, Scallop Join, Flat Braid Join, and more!
 
And I think it looks like little windows with pretty curtains - but the modern, graphic style will work with tons of patterns!
 
For the hook and yarn, use whatever you’ve been using for the rest of your project. :)
