This pattern produces a round carpet that is actually a spiral.

I used 1500 meters of cotton string (3 mm thick) and a 5 mm crochet hook (size H in the US) to obtain a diameter of 96 cm (38 inches). The pattern has 41 rounds and is very easy. The whole work took me about 9 hours.

The carpet is worked in a spiral, so as to avoid that ugly seam running from the center to the edge. Remember: don’t close any rounds with a slip stitch.

You can use any yarn, but remember one thing: the crochet hook needs to be almost twice as thick as the yarn. If you use a yarn of different thickness than my 3 mm cord then the diameter will change, but I can’t predict by how much.

This pattern has been first published in Polish on my blog in March 2023:

In this tutorial I included photos for the first 10 rounds to get you started. After that you have to make do with written instructions and a chart. If any of the photos in the PDF file seem too small, you can find their bigger originals on my blog :)
