This is the crochet pattern to make the Wallis bag. This bag uses Tunesian entrelac stitch.

For this bag I used leftovers Yarn and Colors Epic and a 4,5 mm hook. In the pattern are 3 different colours ways:
Summer flowers: 009, 015, 017, 031, 038, 040, 047, 104, 108, 109
Sunset: 014, 015, 078, 079, 080, 090, 107, 121, 127, 139
Soft pastel: 009, 042, 043, 101, 105, 111, 118, 126, 127, 139

With this yarn, hook and following the pattern, the bag will be about 33 cm by 36 cm.

The PDF version of the pattern has a written pattern and photo tutorials on the different elements of the pattern as well as on tunesian entrelac stitch.
