Mettler 40wt 109yd 2927-1260 Poly Glow - White/Green

POLY GLOW is a phosphorescent, washable embroidery thread that stores UV and artificial light, making embroideries and seams glow in the dark. The thread is extremely well-suited for extraordinary effects on sports-, kids-, and leisure wear, bags and satchels as well as for embroidering logos and lettering. Recommended needle size: 70-80.  Perfect for adding a spooky "glow in the dark" effect on Halloween quilts or any other quilt that could benefit from a little eerie glow.
