crochet handbag and backpack

The bag easily transforms into a backpack and/or shoulder bag. Shades are blue and teal to dark blue at the base.
For the photos, I've arranged the bag with matching accessories - a necklace and bracelet.
It is handy for documents and equipment. It has the following parameters: 
Height inside from bottom to zipper is 34cm. Bottom - 23/12,5cm. Inside there are: two large pockets 23/22cm h with magnetic buttons; 2 small side pockets - 2x12,5/22cm; and one small top pocket - 16/8cm. The bag has interchangeable handles - knitted, with a piece of leather in the most sensitive area. The straps in the backpack and/or shoulder version are again leather. They have an adjuster for length adjustment. On the two front sides there are removable accessories - in the colours of the bags. 
The bag has a zip.
