The bandana is crocheted using granny squares.
You can use any yarn suitable for crochet hooks from 2.25 to 2.75 mm.

The yarn left over from other projects is ideal, provided that the thickness of the thread is the same.

APPROXIMATE YARN CONSUMPTION:
To make it clearer, I will name the colours used for the white bandana:

• The main colour (white) - 60 to 80 grams;
• Yellow - from 20 to 40g;
• Blue - from 10 to 20g. The square after blocking measures 7.5 by 7.5 cm. This pattern has all the diagrams and video highlights.
