A very simple pattern, accessible to people who are middle beginner to crochet (who already know the stitches). A flat cushion, firm and soft at the same time, which can be used on a chair, a bench or on the ground, on a terrace. It can even be rolled up and put in a backpack for use during a hike. It is presented here in a very thick wool but it can also be made of cotton, which will make it firmer and stiffer. You can multiply them by changing the two colors for each cushion or keep only two main colors but change the order of these colors in the cushion. The explanation PDF contains 7 diagrams, one general and 6 of details, as well as 52 photos that show the realization step by step.
