This is a stitch tutorial, not a definite pattern. More like a "recipe", this stitch is very easy to crochet, there is an inherent logic to it, once you complete the first few rows, you'll be good to go. My friend's mom made these for her and her sisters in the 70's and 80's.
Tips: any hook/yarn combination you want to use
**To get the best show for your work, I do recommend to use 1 light color and one dark color ie: black and white or pink and brown or green and peach, etc. Using 2 similar toned colors like blue and purple or pink and yellow will not show the stitch as easily as the contrasting will.
You will need 2 colors, color A and color B.
