Flattening a paint by numbers canvas is often necessary before you begin painting to ensure a smooth, wrinkle-free surface. A flat canvas makes the painting process much easier and improves the final result.
Effective Ways to Flatten Your Canvas
Creases and wrinkles can occur when a canvas is folded for packaging. Fortunately, several simple methods can help you get your canvas perfectly flat and ready for painting.
Method 1: Using Weight and Time
This is a straightforward and highly effective method, especially recommended if your canvas has stubborn folds.
- Utilize Heavy Objects: As suggested by one option for unwrinkling your painting with number canvas, a great way is using a big pile of books to flatten the sheet as much as possible.
- Flat Surface: Start by laying your wrinkled canvas on a completely flat surface, such as a sturdy table or the floor.
- Apply Pressure: Use large, heavy objects, like a stack of heavy books, wooden boards, or even weighted mats, to weigh down firmly on the creases and the rest of the canvas. Ensure the weight is distributed evenly.
- Be Patient: For the best results, leave the heavy objects on your canvas for at least 24 hours. For deeper creases, you might even leave it for 48 hours or longer.
This method relies on consistent pressure over time to gently coax the canvas fibers back into a flat shape without introducing heat or moisture.
Method 2: Gentle Ironing
Applying gentle heat can also help relax the canvas fibers and remove wrinkles.
- Use a Protective Layer: Never iron directly on the printed side of the canvas. Place a clean, thin cloth (like a cotton pillowcase or tea towel) over the back side of the canvas.
- Low Heat Setting: Set your iron to the lowest heat setting. Do not use steam, as excess moisture can damage the canvas or the printed lines.
- Iron Carefully: Lightly press the iron onto the cloth-covered canvas back, moving it slowly over the wrinkled areas. Avoid staying in one spot for too long.
- Check Progress: Lift the cloth periodically to check if the wrinkles are coming out. Repeat as needed until the canvas is smooth.
This method requires caution to avoid damaging the canvas or the printed numbers and lines.
Method 3: Reverse Rolling
If the canvas was rolled with the printed side inward and has a tendency to curl, rolling it the other way can help.
- Gentle Counter-Roll: Carefully roll the canvas in the opposite direction from how it was packaged, with the printed side facing outwards.
- Secure and Wait: Once rolled tightly (but gently), secure it with rubber bands or tape.
- Allow Time: Leave the canvas rolled in the reverse direction for several hours or overnight.
This method is most effective for canvases that are curling rather than having sharp creases.
Why Flattening is Important
A flat canvas provides a stable surface to work on. It prevents paint from pooling in creases, makes it easier to paint within the lines accurately, and ensures your finished artwork looks smooth and professional when framed or displayed. Taking a little time to properly flatten your canvas before you start painting will significantly enhance your painting experience and the final outcome.
