Handy Tester Tabs

Clothing stores often sell dresses with a tiny packet that contains a button sewn into a piece of fabric. While most of us are familiar that the extra buttons are substitutes for the stitched buttons in case one of them falls off, we are still ignorant about the fabric’s purpose.

It turns out; it is there for use as a tester against the effects of our various laundry products. The small piece helps check if the fabric can sustain the detergent’s impact that we usually use to wash our clothes.
