After You Color Your Alien Coloring Pages
- Build a mini space gallery: Mount finished pages on black cardstock, add white paint splatter for stars, and label planets, craters, and constellations.
- Turn art into crafts: Make bookmarks, party invites, stickers (with label paper), or a DIY sci-fi comic by sequencing your favorite pages.
- Try mixed media: Layer crayons for base colors, add marker outlines for pop, and finish with gel-pen highlights for glowing lights and control panels.
- Practice “glow” effects: For moons, thrusters, and tractor beams, blend light yellows or blues outward and soften edges with a cotton swab.
- Make it educational: Add vocabulary (meteor, orbit, galaxy, asteroid, rover), label the UFO parts, or compare planets like Mars and Saturn.
- Protect favorites: Laminate to create placemats or dry-erase travel boards kids can reuse on the go.
