The original site for the pattern is in Danish, but if you use Google Translate it works well. The tutorial itself is pretty simple but the pictures show how to make a basket out of crochet yarn and clothesline beautifully.

A note on the yarn used: The creator of the site calls it ‘crochet yarn’ but doesn’t give a size or amount that they used. I would suggest a cotton yarn on the thinner side to fully duplicate the basket, but really any size could be used to achieve a custom look. Don’t forget to get the clothesline/rope as well!
