The Quatro carpet measures 160x160 cm (in inches: 63x63). For the entire project you will need 1400 meters (1532 yards) of 5 milimeters thick cotton string: 1300 meters of undyed string and 100 meters of gray string, or any other color you like. I use the same kind of string they put in sweatshirts to tighten the hood.

I used a plastic 10 mm crochet hook (US: size N/P, UK: size 15). The whole work took me about 15 hours.

The carpet is done in two parts: the outside frame and the inside filling, both parts being done in the round. It’s best if you sit on the floor the entire time, you can then iron parts of the carpet with your behind ;)
