To flatten a diamond painting canvas, you can follow these steps:
Gather the necessary materials: You will need a clean, flat surface, a soft cloth or towel, and some heavy books or weights.
Lay the canvas on a clean surface: Find a clean, flat surface, such as a table or desk, where you can work on the canvas. Ensure the surface is clean to prevent dirt or debris from getting on the canvas.
Smooth out the canvas: Gently unroll and lay it flat on the surface. Smooth any wrinkles or creases using your hands or a clean, dry cloth. Start from the centre and work towards the edges, pressing down to ensure it lies flat.
Apply some weight: Place some heavy books or weights on top once the canvas is smoothed out. This will help to flatten the canvas and keep it in place while it settles. Please ensure the consequences are evenly distributed to avoid uneven pressure on the canvas.
Leave it for some time: Allow the weights to sit on the canvas for a few hours or overnight. This will give the canvas enough time to flatten and remove any remaining wrinkles or curls.
Check the canvas: After the designated time, remove the weights. Inspect it to ensure it is completely flat and free of any wrinkles. If you notice any stubborn wrinkles or curls, you can repeat the process or use a gentle ironing technique.
Note: If you use an iron, set it to a low heat setting and place a thin cloth or parchment paper between the canvas and the iron to prevent any damage to the adhesive or plastic covering.
Please remember to be careful when applying heat, and always test on a small, inconspicuous area before ironing the entire canvas.
By following these steps, you can flatten your diamond painting canvas effectively.
