For those who know about ribbons and have been working with them for a long time, they can often tell what material and quality they are made of by touching them. But for those who are new to ribbons, they may need to learn some simple ways to identify them:

Method

Chromatic Aberration Test: Visually observe that there is no feminine and masculine colors on the face of the belt, and the color and texture of the belt, the needle edge and the cloth edge cannot be exchanged.
Wool: The 2 sides and surfaces of the ribbon should not have serious filaments or hairballs that affect the ribbon surface by visual inspection.
Jump Stitch: The ribbon should not have jump stitch by visual inspection.
Pollution: The surface of the ribbon should not be contaminated with oil, stains and dust by visual inspection.

These methods are general methods for visually judging the quality of the ribbon.
