They are made of different colors and with different shapes, to start with a square it is necessary to have the appropriate materials and of course the pattern of the sample, every pattern starts from the center.

For a sample of a standard size, start generating a knot followed by four chains, the same can be done with a magic knot, the idea is to have a starting circle, this example is generated using only high points, remember that the points are worked low multiples and that must be precise in each round, after the four chains you

must make twelve double crochets, when the thread is thick you will already be able to appreciate a knitted circle of a special measure, to close this second row of twelve stitches it is closed with Slip stitch, go up with chain and if you are going to use another color you can do it now or continue.
