From the thread you use to attach the button of your shirt that has gone missing to the threads garment factories use for sewing your clothes, every kind of twine is dyed at Bakalia Miakhan Nagar in Chittagong. The yards of the small factories are a festival of colour and workers are busy dying yarn. Some are rolled onto small paper cylinders for use in sewing machines and use by hand while others are rolled on to much bigger rolls for use in large industrial machines.
