A V-Groove is a thin decorative line cut into the face of your top mat, tracing an unbroken rectangle that frames the opening around your artwork. It shows up as a fine white line on standard mats, or a black line when you choose a blackcore mat.
V-Grooves add a subtle sense of formality and craft — a classic framing detail that draws the eye to the piece and gives it a more finished, gallery-quality look.
Note: V-Grooves are only available on the top mat. If you've chosen a double or triple mat layer, the groove will appear on the topmost mat only.
