A gift that reveals itself
Make a puzzle around something they love, like a favorite bird or a place they keep talking about. Describe your idea, or upload a photo for a personal surprise.
Make a gift puzzleTips for a clear puzzle
- Choose one clear subject. A close-up of your dog will read better than a crowded group photo.
- Use a well-lit photo with a simple background. Heavy shadows can hide the details you want to keep.
- For text ideas, try words like "bold colors" and "simple background." Small details can get lost in the grid.
- Print the color guide in color. Keep the answer key separate if you want the picture to stay a surprise.
