How to choose the key settings

Bead width
More beads means more detail but more work. Go larger for portraits, smaller for icons.
Palette brand
Pick the brand you actually own so you can source every code in the result.
Color merge strength
Stronger merging means fewer stray colors and easier building; lower it for more detail.

Why multiple options are generated

For the same image, "maximum detail" and "fewest colors, easiest to build" usually conflict. DuoPinDou generates several options with different priorities and scores each, so you choose by the balance of fidelity and buildability instead of getting one result you can’t judge.

What the export includes

Printable pattern PNG
With grid, coordinates, and a color-code legend — print and build directly.
Bead-count list
How many beads of each code you need, for prep and shopping.
Option scores
Fidelity and buildability scores to judge whether an option is worth building.
