How To Make A DIY Canvas Art Frame

WHY FRAME A CANVAS?

I’m in love with it, but when I propped it up on my mantle, it looked unfinished and kind of lost on the wall.

It was obvious that it needed a frame to look its best. Something to give it structure and to keep it from looking blah and blending in.

Here’s the eye-opening part – whether using a premade frame or having one custom made, art frames are expensive! For example, this one from Overstock, that’s large enough to fit my canvas, is $349.

I needed to figure out how to cheaply frame a canvas print!

You’ve probably seen many people use trim, and nothing else, from the home improvement store to create a frame. That works well for art prints because they don’t have much depth to them.

But wrapped canvas art is a different matter. It’s deeper, which means that the frame needs to be deep enough to allow the canvas to fit inside of it and for back of the canvas to be flush with the back of the frame. Most canvases are 1½” thick, but measure yours to be sure.

We came up with a way to create a frame that is deep enough to accommodate the thickness of a wrapped canvas, using inexpensive wood trim

THERE ARE TWO TYPES OF FRAMES

This tutorial is for a flush mount versus a float frame canvas. 

Flush mount means that the sides of the frame “hug” the canvas – there isn’t a gap between the canvas and the frame. Like the one below.

Pin

Float mount means there is a gap between the canvas and the frame that is intentionally created to give the appearance of the canvas “floating” in the frame. This look is usually achieved using a spacer or inlay of some kind. Like the one below.

To create a flush mount frame, we’re actually going to be making two frames and joining them together. One will act as the back part of the frame, and will give the depth needed to accommodate the thickness of the canvas. The other will be the front, decorative part of the frame.

MATERIALS NEEDED TO FRAME A CANVAS

Here is a list of what you need to make a frame for your canvas.

TOOLS:

Power tools always make wood working projects easier, but this project can totally be done without them!

Pin

Power miter saw or miter box and saw set (I recommend THIS ONE)

Brad nail gun and brad nails or hammer and finishing nails

Nail set – if you use a hammer and nails instead of a brad nailer

Drill or screwdriver

Tape measure

WOOD:

Note that the lengths and number of pieces of wood and trim that you need will depend upon the size of your canvas.

TIP: When shopping for wood, it is important to make sure that each piece of wood is straight and is not warped or twisted!

2″ x 2″ pine lumber – 2″ x 2″ lumber actually measures 1½” x 1½”

Wood trim/millwork that is at least 2″ wide (you want trim that is wider than a 2×2) – we used THIS exact trim.

TIP: Look for 2×2’s with as few knots as possible, preferably none, even if you have to pay a little more for premium lumber.

HARDWARE:

4 – 2″ or longer wood screws

Wood filler

Sand paper or sanding block

Clamps – I own and love THESE

Wood glue

Spray primer (optional) – THIS one is my favorite.

Spray paint – I recommend using paint, instead of stain, for this project because the two different types of wood (the 2×2’s and the wood trim) will not stain the same color. I used THIS one.

MAKE A BASIC 2 X 2 FRAME

The 2×2 frame will act as the back part of the frame and will “hug” the canvas. It will serve to provide the depth needed to accommodate the thickness of the canvas.

Pin

• Measure the exact width and height of the artwork to determine the frame measurements. 
• Cut the 2×2 pieces of wood to fit around the outside of the frame of the canvas. The ends can be butted up against one another and don’t need to have mitered corners.
• You’ll want this frame to be sturdy, so attach the frame together at each corner using wood glue and a wood screw.

TIP: Pre-drill the hole for each screw to prevent the wood from splitting.

Pin

TIP: Be sure to wipe away any excess glue while it’s wet.

• You’ll want what will become the visible, outside edge of the frame to be as smooth as possible, so seal any knots with a primer like THIS ONE, fill them with wood filler, allow to dry and sand smooth.

LESSON LEARNED: Sand the entire side of the wood that will be the outside of the frame, even if there are no knots. We made the mistake of not taking this step and you can see the roughness of the wood if you examine the frame closely. Fortunately, our framed canvas sits high on the wall, above the fireplace, so it’s very unlikely that anyone will ever notice.

• When the frame pieces are completely assembled, do a dry fit by inserting the canvas into the frame to make sure it has a snug fit.
• Remove the canvas from the frame.
• Optional – spray the completed frame with spray primer to prevent the finish coat of paint from seeping into the wood.

CUT THE TRIM WOOD

The most complicated part of this whole process is calculating how long to cut each length of trim because of the mitered corners.

Here’s what one looks like. There’s a formula for you below.

Pin

A perfectly mitered corner requires a 45° angle to be cut on each end of the wood. When the two pieces are joined, you’ll have lovely, professional looking corners.

CLICK HERE for how to cut miters with a manual miter box.

The canvas will ultimately sit inside of the 2×2 frame so that it sits flush with the back of the frame. You will see the sides, but what you will see from the front is the decorative wood trim frame that you’re going to make. 

You are going to be using four boards to make the frame, but keep in mind that you’ll be making a mitered cut on the end of each board, for a total of eight cuts.

TIP: Experiment on scrap wood pieces if you aren’t familiar with how to make 45° angle cuts. When cutting the pieces that will actually become the frame, cut them slightly longer to start with, dry fit them together as you go and trim down any pieces that are too long. 

But the mitered corners against one another and continue, until you have all four trim boards attached to the 2×2 frame.

The finished frame will look like this:

Pin

Because the trim wood is wider that the 2×2’s, lining them up with the outside edge is what will create the slight overlap on the artwork.

Pin

LESSON LEARNED: We tried filling the gap on the trim frame and 2×2 frame with paintable latex caulk, but it didn’t completely fill it. We should have used wood filler instead.

Once again though, our frame is up high where I don’t think anyone will notice, but if you look closely in the above picture, you can see the line down the side of the frame.

Be sure to sand all of the wood filler smooth before painting your frame.

Pin

TIP: When using spray paint, don’t try to get 100% coverage with the first pass. To avoid drips or wrinkled areas in the paint, spray several light coats.

Of course, any color that you would like can be used, but I felt gold would look the best with the rest of my decor.

If you’d like an aged finish, you can add antiquing wax to the frame after painting. I wasn’t after an aged look for this project, so I simply painted mine with THIS spray paint.

The right shade of gold spray paint can be hard to find, but I’m very happy with the one that I used!

ADD HANGING HARDWARE

There are all types of picture hangers for art available. I love using D rings and picture hanging wire whenever I can. It’s so easy!

Simply add a D ring to each side of your frame, making sure that each one is the same distance from the top.

Pin

Then add picture frame wire between the two D rings. 

TIP: Check the length of the wire. You don’t want to wire to show above the top of the piece of art when it’s hung.

Pin

INSERT THE ART INTO THE FRAME AND HANG

When we planned this project, I assumed that we were going to need to add corner braces to hold the canvas in the frame. However, the wood frame is just the right size for a nice snug fit on the pieces of artwork, so no braces were necessary.

Pin

If you find that you do not have a snug fit, you may want to either attach a small triangle of wood in the corners or nail the canvas to the frame from the inside on the back.
