How to Assess the Severity of Canvas Wrinkles: Are You Dealing with a Minor Nuisance or a Major Disaster?
Before you start trying every trick under the sun, let’s take a moment to assess the situation. After all, you wouldn’t use a sledgehammer to crack a walnut, right? The severity of the wrinkles on your painting by numbers canvas will guide you to the most effective method.
Mild Wrinkles: The Subtle Annoyance
- Appearance Features: These are the kind of wrinkles you see on a canvas that’s been a little too cosy in its packaging or storage. We're talking about light, shallow creases that look like someone ran their fingers across the fabric. It’s like the canvas took a nap and just needs a good stretch. They don’t affect the texture much, so when you paint, your brush won’t skip like it's trying to avoid a pothole.
- Possible Causes: A little pressure from packaging, or the canvas being in one place for too long. No biggie, it’s a common issue.

Severe Wrinkles: The Canvas Version of a Bad Hair Day
- Appearance Features: Now, these are the wrinkles that could make a grown artist weep. Deep folds, indentations, uneven bumps—basically, the kind of creases that refuse to be ignored. If you try to paint on these, it’ll be like trying to paint on a bumpy road. Brushstrokes will be uneven, colours may not blend as they should, and you might just end up wishing you never even started.
- Possible Causes: Transport mishaps or a canvas that's been improperly stored for too long can lead to these tough wrinkles. Sometimes, it’s as if your canvas went through a mini war—tugged, pulled, and bent beyond its limits.

Once you've assessed whether you’re dealing with mild or severe wrinkles, you're halfway to solving the problem!
The Best Methods to Get Wrinkles Out of Canvas: Solutions for Every Situation
Alright, now that you know what kind of wrinkles you're dealing with, it's time to roll up those sleeves (and not your canvas, please!) and get down to fixing it. Below are some tried-and-tested methods, from the quick fixes to the more involved solutions, each with clear instructions to guide you through the process—because, trust me, you don’t want to be winging this.
Method 1: The Steam Iron Approach
Tools Needed:
- A steam iron or a handheld steamer
- Damp towel
- Paint by numbers canvas
Steps
- Prep your canvas: Lay your paint by numbers canvas flat on a smooth, heat-resistant surface, like an ironing board or a sturdy table. The important part here is to make sure that the surface can withstand heat.
- Dampen the towel: Soak a towel with water and wring it out so that it’s damp but not soaking wet. This towel will act as a shield between your steam and the canvas, so make sure it’s moist enough to provide steam but not dripping.
- Steam the back of the canvas: Place the damp towel over the back (NOT the front!) of the paint by numbers canvas. The back of the canvas is more resilient to heat and moisture, so it’s the best place for steam treatment. Using your handheld steam iron (or a steam iron), hold it a few inches above the towel, and gently release steam over the wrinkled areas.
- Let it cool down: Once you’ve finished steaming the back of the canvas, leave the canvas to cool and dry completely. Let it cool fully before you start handling it—this allows the canvas fibres to settle, and the wrinkles to smooth out properly.
This method works wonders for light wrinkles. Steam helps loosen the fibres without damaging the paint. For deep wrinkles, you might need a more heavy-duty method.
Method 2: The Standard Ironing Approach
Tools Needed:
- An iron
- Damp towel
- Paint by numbers canvas
Steps
-
Prep your canvas: Lay your canvas flat on a heat-resistant surface, making sure it’s as smooth as possible.
Little reminder: The flatter, the better! You don’t want to press in new wrinkles while trying to fix the old ones. - Prepare the damp towel: Dampen a towel with water, then wring it out so it’s moist but not dripping. Lay it over the back of the canvas, covering the wrinkled areas.
-
Iron with low heat: Set your iron to low heat and gently move it over the damp towel, making sure to keep the iron in motion. Press lightly—let the heat do the work, not the pressure.
Reminder: Never let the iron touch the canvas directly. If you do, you risk damaging the fabric and messing with your painting. Keep it indirect! -
Check and cool: After ironing, check if the wrinkles have softened. If necessary, repeat the process. Let the canvas cool down completely before you touch it or move it.
Little tip: Don’t rush the cooling process. The canvas needs time to hold its shape and maintain that smooth finish.
This method is perfect for mild wrinkles—gentle heat helps smooth things out without too much risk. But if you’re dealing with deep creases, it might not be enough.
Method 3: Dampening and Stretching (For Mild Wrinkles)
Tools Needed:
- Spray bottle
- Stand or easel
- Paint by numbers canvas
Steps
- Mist the canvas (on the back): Lightly spray the canvas with water using a spray bottle, but only on the back side. This will dampen the fibres without affecting the paint surface. Don’t soak it—just a light mist to relax the fabric.
- Stretch the canvas: Lay the dampened canvas flat or hang it on a stand. Gently pull the four corners of the canvas to stretch it out and smooth out the wrinkles.
- Dry and let gravity work: Allow the canvas to air dry naturally for 24 hours. Gravity will help pull the wrinkles out as the canvas dries.
The back of the canvas is where the moisture should be applied to prevent damaging the front (where the paint might be). This is a great method for mild creases, and it’s quick and simple to do.
Method 4: Reverse Dampening (For Deep Wrinkles)
Tools Needed:
- Damp cloth
- Large flat frame (wooden frame or easel)
- Paint by numbers canvas
Steps
- Dampen the back: Using a damp cloth, lightly wipe the back of the paint by numbers canvas. You want the canvas to be slightly moist, but not soaking wet. This helps loosen the fibres and prepare them for stretching.
- Hang the canvas: Hang the canvas on a frame or easel. Let gravity help stretch the canvas, which will naturally reduce the wrinkles over time.
- Leave it for 24 hours: Let the canvas hang and dry completely for 24 hours. Gravity will slowly pull the wrinkles out as the canvas dries.
This method is perfect for deep wrinkles that won’t disappear with simpler techniques. It’s a longer process, but it’s highly effective for stubborn creases.
Method 5: Weighted Pressing (For Mild Wrinkles)
Tools Needed:
- Heavy books or canvas clamps
- Paint by numbers canvas
Steps
- Lay the canvas flat: Place the painting by numbers canvas on a flat surface, ensuring it is spread out evenly without any obvious folds.
- Apply weight: Place heavy books or other objects on top of the wrinkled areas. You want the pressure to distribute evenly across the canvas, helping to flatten the wrinkles.
- Leave for 24 hours: Let the weight sit on the canvas for 24 hours to allow it to smooth out naturally.
This method works best for lighter creases, and it’s ideal when you have the time to let the canvas rest under pressure.

Method 6: The Hairdryer Approach (Blow Those Wrinkles Away!)
Tools Needed:
- Blow dryer (Hairdryer)
- Paint by numbers canvas
Steps
- Mist the canvas: Lightly spray the painting by numbers canvas with water using a spray bottle. You don’t want to soak the canvas—just dampen it enough to get the fibres loosened.
- Heat it up: Set your hairdryer to a low heat setting, and hold it a few inches away from the wrinkled area. Move the hairdryer around in a circular motion to avoid overheating one spot. The heat will help the dampened fibres relax and smooth out.
- Smooth it out: Gently smooth the canvas by hand while the heat is applied. Be sure to move quickly to avoid damaging the fabric. Once the wrinkles begin to fade, let the canvas cool before touching or moving it.
This is a great option for small wrinkles, and it’s the fastest way to treat your paint by numbers canvas if you’re in a pinch. Just remember to keep the heat moving and avoid holding the dryer in one spot too long!
