Claude Opus 5.5 · October 27, 2026

Logan Graphic Products (brand)

Logan makes beginner-friendly tools that work together for every home framing step: mat cutting, mitering, joining and fitting.

Not for: Shops framing in volume, which need wall-mounted cutters and pneumatic underpinners from professional framing suppliers.

Lineco Hayaku (line)

Japanese paper hinges and water-activated adhesive make this a versatile choice for conservation-minded matting and framing.

Not for: Water-sensitive artwork or projects requiring instant, dry application.

Stack depth vs rabbet. Glazing plus mat plus artwork plus backing must fit within the frame's rabbet depth. If the stack is too deep, the points cannot hold the package flat and the backing bows out.
Archival rating of anything touching the art. Mats, backing and tape that touch the artwork should be acid-free and lignin-free (alpha-cellulose or cotton rag). Regular paper-core materials yellow and burn the artwork over time.
Standard sizes. Plan around standard frame and mat sheet sizes (for example 32x40 inch mat sheets). Standard sizes cut waste and let off-the-shelf glazing and backing fit.

Shops seen in search results on November 5, 2026. A shop missing here may sell it too. Nothing was checked by a person.

Logan Graphic Products: The usual home and studio framing tool range.
Fletcher-Terry: Professional-grade point drivers and cutters.
Crescent: Widely stocked mat board, including conservation and museum grades.
Nielsen Bainbridge: Aluminum sectional frames and mat board.
Larson-Juhl: Professional wood moulding supplier.

Do I need an expensive kit to frame at home?

No. A mat cutter, a straightedge and a point driver cover most home framing if you buy ready-made frames or sectional frames.
