The studio draws random curvy lines that cross over each other. Every space the lines make is yours to decorate. Pick a design, pick your colors, and tap a space.
More crossing points = more, smaller spaces to decorate. Try 20 for a quick one, 80+ for a challenge. You can add your own lines any time.
Quick fill: tap a space and a whole design fills it.
Tap any space. Change the design or colors and the space you just tapped (the blinking one) updates too.
The blank coloring page has just the lines, ready to print and color by hand. Your drawing is saved on this device, so you can come back to it.
