So, I came across this crochet technique tonight as I was catching up on Facebook posts on my page. It's called Bargello (Florentine) Crochet since it is based on the needlework technique of the same name. By using multiples of some basic crochet stitches at various heights and widths, you can create a pixelated effect and the illusion of waves. Bobwilson123 has created a free video tutorial, and you can download the written pattern for free from this link on her website. Mmmm, I'm getting inspired, watch out!
