1. Cover the numbers with a white pencil
 Are the numbers in the light-colored area easy to show through? Use a white sketch pen to cover the numbers and then color them.

2. Transparent primer to increase adhesion
 Apply transparent primer (Clear Gesso) to increase the roughness of the canvas and improve the adhesion of the paint (let it stand for 24 hours to dry).

3. Thinner to revive dry pigments
 Is the acrylic paint thickening? Add professional thinner (more resistant to cracking than water) to save the dried paint cans.

4. Removable drawing board to stabilize the canvas
 Use A3/A2 drawing board or desktop easel to fix the canvas, and switch freely between indoor and outdoor creations.

5. Practice with excess paint without wasting it
Apply the remaining paint on a blank canvas to practice gradient/color mixing, and practice techniques beyond the limitations of numbers.

6. Zoom in the details with your phone
Can't see the small numbers clearly? Take a photo and zoom in on your phone/tablet to avoid missing small areas.

7. LED magnifier protects eyesight
Use a head-mounted LED magnifier (3X-5X magnification) for precision areas to reduce eye fatigue.

8. Low-temperature ironing to smooth wrinkles
Canvas wrinkles? Iron the reverse side at low temperature (do not exceed the cotton and linen setting) to protect the coating and digital printing.

9. Monochrome segmentation to prevent drying
Open only one can of paint at a time, and seal immediately after painting to reduce hardening caused by air contact.

10. ZigZag gradient technique
Use Z-shaped cross strokes in the transition area:
① Draw a B-color slash in the A-color area → ② Draw a A-color reverse slash in the B-color area → ③ Use a clean brush to lightly sweep the mixed junction
