A simple crochet project suitable for crochet beginners. For the bag to look nice, you will have to line it, which requires some sewing experience - I have prepared a tutorial to help.
For the original Caramella I have used exactly one skein of Lang Quattro Colour yarn. For Granita variation (in single crochet) I have used 1,5 skeins of Lang Yarns Golf Color.
If you would like to substitute with another variegated yarn, I suggest making sure the colour sections are quite short.
Details about modifications for Granita can be found in this post.
