From the blogger: "This square may be labeled intermediate due to the post stitches, but it's actually pretty easy to crochet! The varying stitch heights create a fun color pattern, while the post stitches give the overall square some texture. Try playing with different colors or even making the whole thing in one color. Just have fun with it. Once you finish the stitches, cut the yarn and weave in all ends. The finished piece after blocking should measure to be a 12” square. Enjoy!
