OK, now this is funny. Craftster user Ajmaley came across some glow-in-the-dark embroidery floss and decided to make this delightfully wicked cross stitch that’s all rainbows ‘n’ unicorns by day, angry monster face by night. I like her (jokey!) idea of pranking a kid with it, though some parents might understandably feel otherwise. Link.
