all you need to have is paint ,brush,canvas,artificial leather and liling cloth
You will have to first make a paintings as per your requirement ...I have made the flying birds..flowers etc on a canvas .
cut out the canvas painting with the design on top and with a plain back as per the design of the bag you would like to .
make the bag patten and stitch accordingly...
CANVAS is used for wall painting ..however i have used for bags...see how beautiful it looks.
