For crocheting an organizer, you need about 400 grams of various yarns. For the main fabric (background) you need 200 grams of yarn of average thickness of white.
In my study guide there is a drawing and description of crocheting all the details of such an organizer. Acrylic or cotton yarn of medium thickness is suitable for crocheting.
Height from horn 24 inches (61 cm), width 13 inches (33 cm)
The upper ribbons (12.5 inches or 32 cm) are tied to the head restraint, holding the bulk, and the lower ribbons (24 inches or 61 cm) help the canvas fit snugly against the back of the chair.
The pattern is written in American English crochet terms. In the table of terms there are symbols in English, British and Russian languages.
