Lovely bag with a large leaf pattern, that is very satisfying to crochet. The bag is made from the bottom-up in from/back post double crochet, also known as embossed crochet. Here it is shown with crocheted straps, but you could also add leather straps instead.
The pattern has written instructions and a chart so you can use whatever you prefer.

Yarn: 6 skeins Kreadeluxe organic cotton (165 m/50 g) - if you use leather straps instead you will only need 5 skeins.
Hook: 3 mm

The pattern is available in english (US terms), german and danish
