Isn't this a beautiful bag with a long strap to wear over your shoulder. This medium sized mochila inspired bag will be 31 cm/12.2 inch high and the diameter is approx. 17 cm/ 6.7 inch. The strap is 4,5 cm/1,78 inch wide and 125 cm/ 49 inch long.
You have to use the 'yarn under technique' and the back loops of the stitches only. And you have to crochet with 2 or 3 threads at the same time.
There are pictures of the 'yarn under technique' and diagrams of the patterns available in the pattern. Also is explained with pictures how to make the tassels.
I’ve made this pattern with yarn for hook C2 /11 or 12 (= 4 ply) and hook C2/12 (=2.5 mm hook). You need: 100 grams off white cotton yarn (=250 meters/273 yds), 150 grams brown cotton yarn (=375 meters/409 yds) and approx 100 grams blue cotton yarn (=250 meters/273 yds). I’ve used Scheepjeswol Larra.
