There's a bench along the back wall with a felt mat on it gone grey with handling, and on the felt a scatter of offcuts — corners of gesso moulding, a curl of acid-free tissue, a rectangle of window-mat board with a bevel cut clean through it, cream on the face and a startling white where the blade has exposed the board's own core.

Nobody's manning the bench right now. A radio somewhere is playing something with too much reverb on it, turned low, the kind of station nobody chose on purpose.

I have been in a lot of galleries. This is the first framing workshop I have ever been allowed into, and I want to tell you immediately that it is more interesting than most of the galleries.

The Room

This room doesn't have the hush the two front galleries have.

It has a compressor cycling on and off. A rack of glass leaned at an angle against a padded wall. A mat cutter bolted to a bench with a steel straightedge worn silver along one long edge from years of a blade riding it. Boxes of hardware, D-rings and wire, stacked by size. A tape measure clipped to a belt hanging off a nail.

It smells of dust and something faintly solvent, and under that, glue.

Watching a Mat Get Cut

There's someone here after all — back with coffee, gloves already on.

The blade goes in at an angle, not straight down. Forty-five degrees, so the cut edge — the bevel — catches light and throws a thin white line around the opening rather than a flat dead one.

She measures twice before she cuts once, which is the only cliché in this room that turns out to be true every single time.

The border comes out at two and a half inches on three sides and just over three on the bottom.

Not a mistake. A habit.

The bottom is always a little heavier than the rest, because a mat cut dead level on all four sides makes the eye feel the image sliding downward — and nobody wants their painting sliding.

She doesn't explain this. She's done it enough times that explaining it would take longer than doing it correctly. I had to go away and look it up like a schoolboy.

The Glass Question, Settled By Somebody Holding Two Things

Then she picks up two pieces from the rack without asking me what I want to know — which suggests she has watched people stand here and wonder the same thing before.

In one hand, a small oil study. Thick paint, a visible ridge where the brush changed direction and never got smoothed.

In the other, a print on paper. Flat, matte, a photograph reproduced.

She holds the oil up to a sheet of glass and doesn't put it behind — just holds it near, so I can see how the glass throws the room back at the paint. A soft double image of the strip lighting sitting right over the impasto. Killing the ridge stone dead. Turning texture into reflection.

Then she sets the print into a mat, slides both behind the same glass, and the paper just sits there being legible, being protected, the mat's bevel holding it a hair off the surface so it can't stick if the room ever gets damp.

Same glass. Opposite effect.

The paint didn't need protecting and the glass made it worse. The paper needed protecting, and the glass — held slightly off by the mat rather than resting on the sheet — did exactly its job.

She did that in about eleven seconds and it explained more than any article I had read on the subject, including two I had written.

A Painting I Saw Once

I think of a painting I saw in a house that should have known better. Sealed behind glass in a frame that looked expensive, and gone slightly milky at the centre where damp had got in and had nowhere to go — trapped by exactly the thing meant to keep it safe.

Nobody in that house had done anything wrong on purpose. They'd done the instinctive thing, the thing that protects a photograph, and applied it to paint.

Which doesn't want protecting the same way. Wants to breathe and cure and be looked at without a pane of something reflective standing between it and the room.

The Verdict

Stated flatly, no hedge.

And the rest — mat width, bottom weight, whether you spend twenty per cent more for the coating that also kills the glare — is arithmetic you can do once you've accepted the one rule that isn't arithmetic at all.

Three Things People Ask Me, Standing at This Bench

Should an oil painting be framed under glass?

No.

Oil keeps curing for months after it's touch-dry, and a sealed cavity behind glass traps whatever it's still giving off, along with moisture the canvas will happily hold onto. Glazing also flattens the one thing a painting has that a print doesn't — the physical ridge of paint — into a reflective sheet that competes with the room's own lighting instead of showing you the surface.

The one exception is oil or acrylic done on paper or thin card, where the support, not the paint, is what needs the glass.

How wide should the mat be?

Wider than the frame moulding, as a habit worth keeping — a frame under two inches wants a mat of two and a half or more. Two inches suits small work, two and a half to three suits medium, three to four suits anything large enough to need the extra air.

And cut the bottom ten to twenty per cent heavier than the other three sides. Equal borders make the image look like it's sliding out of the frame, and a slightly heavier foot corrects an illusion most people never consciously notice — only feel.

How much does this actually cost, realistically?

More than the flat-pack option and less than people brace themselves for.

Fixed-size frames from a place like IKEA run under fifty dollars and include a mat and glazing, which is a genuinely honest deal for a print. A custom job from an independent framer typically lands between seventy-five and two hundred and fifty dollars depending on size, with conservation glass adding twenty to sixty on top.

Period frames computed to size rather than picked off a shelf run in the low hundreds for a mid-size piece, with shipping already inside the number rather than added at the end.

None of which touches the antique market, where a real period frame averages over two thousand dollars and the record sits past a million. That's a separate hobby, not a framing decision.

The Sizing Rules, Condensed

Head to Head: What Framing Actually Costs, Across the Market

At the 50 × 70 cm / 16–20 in class, all-in where stated. Three atelier retailers, four independent art vendors, and the high-street options for reference.

Two things fall out of that table that I did not expect before I stood in this room.

First: the cheapest row is genuinely the right answer for a lot of people. Fifty dollars for a frame, a mount and glazing is not a compromise if what you own is a print. It is the correct purchase. This is the rare corner of the art trade where the flat-pack option is not a sad substitute — it is a well-engineered product doing exactly the job the material requires.

Second: almost nobody in the reproduction trade publishes a framing price. Scroll that column. "Not itemised." "Not published." "Not stated." That isn't evasion, mostly — it's that framing prices depend on perimeter and on shipping a bulky box, and a bulky box across an ocean is where the money goes. Which is why the vendors who do publish a number are the ones who've folded the freight inside it, and why the museum makes framing a step in the order rather than a price on a page.

And it is why the advice this workshop would give you, if it gave advice, is the least commercial sentence in the article: buy the picture from whoever makes it best, and get it framed by someone within driving distance of your own wall.

Leaving

She's back to the mat cutter before I've finished the thought, blade going in at its steady forty-five degrees, and the offcut she peels away curls once and lies still on the felt, next to all the others exactly like it.
