Choose three colors to begin.
You do not need a full box of supplies to make an interesting page. Choose one main color, one contrasting color, and a lighter companion. Try green, coral, and pale yellow for a garden design, or navy, blue, and a warm orange for a celestial pattern. These are starting points rather than rules.
Repeat something small.
Give similar shapes a repeated color so the page feels connected. You might color every second petal the same way, repeat one shade around a border, or leave some areas white. A limited palette makes those small decisions easier to notice. Test pencils or markers on a spare sheet before committing to the design.
Enjoy the process at your own pace.
Print a second copy if you want to try a different combination. Use paper underneath the page when working with markers, since ink can bleed through. A finished page can become a card, a folder cover, or a little decoration. You can also stop halfway through and return later; the activity does not need to produce a perfect result.
