Twine Jute Soles. Espadrilles Soles. Rope sole. Real shape foot sole crochet level - Intermediate They are made with a basic crochet stitch All Sizes from US women's 3.5 to US men's 12 * Jute twine – 2.5 mm * 3.5 mm crochet hook /I recommend working with a metal hook/ I used 100 g jute yarn. 85 m, 3 ply. Really measured, yarn labels can sometimes fool you. For a pair of soles I used from 100 g (for the smallest size) to 160 g (for the largest size). You can also use 2 mm jute twine (100 g - 110 m), then you need to change the size schemes. With the size scheme US W- 5.5 you will get size US W-3.5, with the size scheme US W-6.5 - you will get size US W- 4.5, etc. language - English / US and UK terminology/ and German
