In accelerated aging studies, exposure to UV rays have been shown to cause fusibles to tan (darken). Especially on light colors, sheers or other light weight fabrics, and surface use, tanning may read as a color shift or dark spots. But now there’s Mistyfuse Ultraviolet! Mistyfuse Ultraviolet is specially formulated with an effective retardant to protect against the tanning effect of UV rays - without sacrificing any of the inherent Mistyfuse qualities you expect and trust. Mistyfuse Ultraviolet is white and fuses clear.

It's a dream to work with—it handles well, is incredibly sheer, doesn't add bulk to your fused piece and bonds firmly once cooled. And since there is no added adhesive, it will never gum up your scissors or quilting needles. Each package comes with simple instructions for easy fusing with no waste.
