Astrid's big fish blanket

This blanket, inspired by a drawing I made on my own wall at home, is done in interlocking crochet. The pattern is very detailed, and extra files with instructions and tips on the technique itself. It looks complicated, but it is very simple, only using dc+chain 1 (us terms). It is though, on the heavy side, it is done with mercerised cotton and weighs almost 2,3kg. However, you can choose any yarn, though different hooks will affect the size (but not the proportion of the drawing). The finished blanket is approx 1,50 x 1,70m.
