AlixaCrochet
The classic square, round by round. 15 to 20 minutes each once you know it.
Worsted cotton or acrylic yarn in a few colours, a 5 mm hook, scissors and a tapestry needle.
Work four clusters of 3 double crochet into a ring, with 2 chains between them. Those chains are the corners.
In every corner space work 3 double crochet, chain 2, 3 double crochet, with 1 chain between corners.
Pin each square flat and dampen it, so they all come out the same size. It matters when you join them.
Lay them out, join them into rows, then join the rows. Three joining methods are in the full tutorial.
