Golden State Art 9x12 Uncut Photo Mat Boards (50)

These are 9x12 uncut matboards from Golden State Art — a 50-pack of double-sided (black/white), acid-free, 4‑ply backing boards for photo mounting, framing, and craft projects.

Whether you’re preparing prints for display, building presentation boards, or cutting custom mats for a gallery wall, these robust 9x12 backing boards give consistent support and a clean visual finish. Each sheet is approximately 1/16 inch thick (4‑ply) and made to resist bending during handling, while the acid-free construction helps protect photos and artwork from deterioration. One side is black and the other white, offering instant contrast options without needing separate purchases.

How do these mat boards improve my framing and mounting workflow?

The boards provide a rigid, flat surface that reduces warping and makes trimming and mounting easier. Their uniform thickness helps frames sit level and keeps mounted pieces looking professional.

• Stable 4‑ply construction for straight edges and secure mounting.
• Uncut 9x12 size ready for trimming to exact dimensions.
• Double-sided color choice (black/white) for quick visual changes.
• Acid-free material minimizes risk of long‑term damage to photos.

What craft and display uses are these boards best suited for?

They work well as backing for framed photos, as temporary or permanent presentation backers, and as a base for mixed-media or school projects. Their thickness gives projects structure without adding significant weight.

• Photo backing and picture framing support.
• Presentation boards for shows, classrooms, and pitches.
• Craft projects: scrapbooks, collages, invitations, and signage.
• Trim into custom mats, inserts, or stencils for parties and events.

How easy is it to cut and customize the Golden State Art 9x12 boards?

These uncut sheets are designed for clean, predictable trimming with standard craft knives, rotary cutters, or straight-edge tools. The 4‑ply core holds edges well so you get sharp lines after cutting.

• Cut cleanly with a sharp utility knife and metal ruler.
• Holds crease and edge detail for precise mat openings.
• Suitable for die-cutting or hand-cutting to uncommon sizes.
• Black/white reversible faces mean fewer separate materials to stock.

Will these boards protect my photos and artwork over time?

They are acid-free, which helps slow paper yellowing and deterioration compared with non‑archival cardboard. While not museum-grade conservation board, they are an economical choice for safe short- to medium-term displays and storage.

• Acid-free composition reduces chemical degradation.
• Thicker 4‑ply core offers physical protection and support.
• Reversible color option helps avoid extra backing materials.
• Good for storage, shipping support, and everyday displays.

Who is this for? Artists, photographers, teachers, crafters, and DIY home decorators who need a reliable, affordable supply of uncut backing boards will appreciate this 50‑pack. It’s ideal for people who cut custom mats, prepare multiple prints for shows, assemble presentation boards for school or business, or craft event decor. If you want consistent thickness, reversible color surfaces, and acid-free protection without buying individual mats, this pack from Golden State Art supplies practical versatility and value.
