Medium Weight Vs Lightweight Interfacing If you want to add a shape, strength, and structure to medium-weight fabrics, this medium-weight interfacing is all you need. But, if you want durability and structure for your projects having lightweight fabric/material, then lightweight interfacing works well. | Which Side Has the Strong Sticking The shiny side of the interfacing has an adhesive coating that sticks firmly to the fabric for neat results. It looks shiny as it has very tiny glue dots on it, which makes it look a little bumpy/rough as well. So, you can check bumpiness/roughness or shine to find out the fusible side. | Adding Structure, Durability, and Support to Your Projects This non-woven fusible interfacing supports fashionable clothing projects, applique work, quilting projects, home decor designs, various art projects, etc. In every project, interfacing adds stiffness, durability, and holds shape. In other words, grace, sophistication, and strength can be assured with it. |
