Before you start placing your sparkling drills, one thing can make or break your diamond painting experience: a flat, smooth canvas. A creased or curled canvas can make placement frustrating and affect the final look of your artwork. In this guide, we’ll show you how to flatten your diamond painting canvas—especially if you're working with a full drill diamond painting—and keep it in perfect shape throughout your project.

Why Does the Canvas Curl or Wrinkle?

Most diamond painting kits arrive rolled or folded for shipping convenience. While it’s normal, the folds can get in the way. Wrinkles or waves may:

• Cause drills to fall off uneven areas

• Make it difficult to line up drills properly

• Affect the finished look of your DIY diamond painting kit

5 Easy Methods to Flatten Your Canvas

1. Reverse Rolling

Gently roll your canvas in the opposite direction of how it was packaged. Secure with a rubber band and leave it for 30 minutes to 1 hour.

2. Heavy Book Method

Lay your canvas face-down (protective sheet still on) and place heavy books or a flat board on top. Let it sit overnight for best results.

3. Warm Iron Technique (Use with Caution)

Place a cloth or parchment paper over the back of the canvas and use a warm (not hot) iron. Move gently—do not let the iron touch the glue directly.

4. Use a Light Pad

When in use, a light pad flattens the canvas from below and improves symbol visibility, especially helpful for round drill diamond painting.

5. Frame or Tape It Down

If you're ready to start right away, secure the canvas corners to a flat surface using painter’s tape. This also helps when working on large full drill diamond painting kits.
