Then i cut the Tee into this shape:
Used white fabric for making the inner lining of the bag. After a lot of sewing joined the two opposite sides of the Tee keeping the braid end in between. Since god lies in details ;) made a pocket on the inside of the jhola with the sleeve that i had cut off:
one on the outer side with the remains of the neckline:
And finally, made a little deco on the top:
Done (weird lighting is making the bag look blue)!
