this is the very simple, slightly time consuming way of turning your old jeans into a cool bag.
Step 1: You will need...
an old jeans
a sewing machine
thread matching the color of your jeans
pair of scissor
Step 2: Cuttings
try to keep the fabric as straight as possible. don't pull it as it is stretchable. iron if required. I have got a curve edging of my bag if you want straight one cut accordingly.
when you are dine cutting, rip the seam off and separate the front and back part.
and discard the front part.
Step 3: Cuttings continued
open it up and place the back par (which is now front of the bag ) on it as in the pic.
cut it out. now you got the front and the back side of your bag.
now take the remaining part of the leg and mark 2 inch wide strips.
cut out 3 such strips two of length 1 inch more than the sides. and one 2 inch more than the base.
if you are not getting a single long strip you can join two smaller strips. try to use these joined strips for the base and get single strips for sides.
Step 4: Stitching
stitch the edges with a zigzag stitch to secure the work.
now stitch the front of the bag making sure wrong sides face each other. sew the two sides before moving to the base.
Step 5: Handlel
sew the longer edges with a zigzag stitch (you can also cut a wider strip and fold it for a neater look but sometimes it becomes difficult to stitch a thick cloth in the machine)
sew this strip to the side strips making sure wrong sides face each other.
