This one is, in my opinion, the easiest of all the squares. I have used all the basic stitches, but also included clusters and popcorn stitches. The corners are formed working three double treble crochet stitches together in the designated stitches as explained in the pattern. By following the diagram it should not be a problem.
Use the link to the pattern in American crochet Terminology.
The Afrikaans is also available on the same website.
