This border can be used on any stitch count. All you need to make sure is you have corners on your project. It doesn’t matter the number of corners either.

It can be done in any hook size and any yarn weight. Please use the yarn weight and hook size corresponding to and used for your project. Yardage needed may be vary if pattern is done different in different yarn weight.

The corners are important for this border. They are where the design comes in. The sides between each corner are just simple stitches.
They add a bit to the design but are not the main feature of this border like the corners are.

This pattern is written assuming you have 4 corners.
