Fix the pattern before you build

A bead chart that looks “good enough” on screen can still cost you a kit and a weekend if it has a stray bead in the middle of a face, a halo ring around the subject, a seam through the eyes, or twenty near-identical colors you do not own. This guide is a short pre-build pass for any RetroBeads pattern: read the silhouette, clean the obvious problems, check the colors and the seams, then export.

If you have not made a pattern yet, read Create your first RetroBeads pattern first. This guide assumes the chart already exists in the editor and you are about to sort beads or press Export PDF.

What “ready to build” actually means

A chart is ready to build when four things are true:

• The subject reads as itself from across the room, not only when you lean in.
• Flat areas are flat. No stray off-color beads, no soft halo of in-between colors around the edges.
• The color list fits the beads you own, or the substitutions are planned, not improvised.
• The board layout puts seams in calm places, not through faces, hands, text, or hard outlines.

The pre-build pass below is one quick walk-through that covers all four. Run it in the editor before you press Export PDF. Source RetroBeads product RetroBeads editor panels The editor exposes a Colors panel and a Boards panel that this pass uses to check color count and board seams.

Pass 1: Read the silhouette

The fastest pattern check costs nothing. Look at the chart at distance, not bead by bead.

1. Step back from the screen, or squint until small details blur.
2. Ask whether the subject is still obviously the subject. A face should still be a face, a sprite should still be that sprite, a logo should still be readable.
3. If the subject disappears, the chart is too busy or too low-contrast for the bead count. Note that before you change anything else; many later fixes start here.

The squint test is the same maker check used in the photo guide. It works for pixel sources too: a chart that needs perfect lighting and zoom to read on screen will not read better as a tray of beads under a kitchen lamp.

Pass 2: Spot the problems on a problem map

Most pre-build problems come from one of four families: a halo ring of in-between colors around the subject, stray beads in flat areas, a weak silhouette where the subject blurs into the background, and a board seam that cuts through a feature you care about.

Read your own chart against this map. For each family, the fix usually lives in a different place:

• Halo ring. A soft border of in-between colors around the subject. On pixel sources this is almost always anti-aliasing from the original file. Crop tighter, enable Background cleanup in the wizard, or paint over the halo cells in the editor. The pixel-art guide has the full halo walk-through.
• Stray beads. Single off-color cells scattered through flat areas. In Photo mode, Confetti cleanup can remove many of them on import; the rest are faster to erase or repaint in the editor than to chase with another wizard pass.
• Weak silhouette. The subject and background read as one shape at distance. For photos, try Edge outline in the Photo cleanup group or lower Max colors in the Colors panel so the chart commits to fewer shades. For pixel art, the source itself may need more contrast before re-import.
• Awkward seam. Covered in Pass 4 below.

Pass 3: Check the color list

Open the Colors panel in the editor. The list shows every distinct bead the chart uses and how many of each you need. This is the cheapest place to fix color problems.

Three questions to ask while you read the list:

• Are there too many colors? A chart that uses thirty near-identical browns or twenty very close blues is harder to sort, harder to find the right cell for, and rarely looks better at distance. Lower Max colors in the Colors panel until the list matches a number you can actually buy and keep organized. The app picks representative beads first, which is closer to what you want than a sprinkle of every option. Source RetroBeads product RetroBeads advanced conversion options Max colors caps how many distinct beads the chart uses and is adjusted in the Colors editor panel after import.
• Does the palette match the beads you own? A chart matched against a 200-color brand will not just “work” with a 60-color starter kit. Switch palette to the beads you actually have before judging the preview, then run Pass 1 again.
• Are any colors missing from your stock? Decide the substitution now. Start inside the selected RetroBeads palette by lowering Max colors or repainting cells with a color you do own. Only cross brands or series when the maker decision is intentional. The brands, colors, and pegboards guide walks through swap rules, protected zones, and series compatibility in detail.

If you find yourself wanting to change Color matching, Dithering, Downscaling, or a Photo cleanup toggle, that is a re-import, not a Colors panel fix. Change one control at a time and run the squint test again before judging the result.

Pass 4: Check the board seams

Open the Boards panel. Multi-board projects always have seams where boards meet. A seam that runs through a face, hand, word, or hard outline can read as a visible split in the finished piece.

Walk the seams in the preview and look for protected zones:

• Faces and hands. Eyes, mouths, fingers. Any human or character feature.
• Text and logos. Letterforms read poorly when a letter is split between two boards.
• Hard outlines. A continuous dark line that helps define the subject. A seam in the middle of that outline can show.

If a seam falls in a protected zone, you have three moves: shift the framing in the import wizard so the subject sits in one board, change Boards wide or Boards high in the Boards panel so the seam moves into background, or accept the seam and plan the tape method for that joint. The tape method guide covers seams that are unavoidable.

Board count is a related check. A chart that needs more boards than you own, or more boards than you can hold under one iron, is a build risk too. Drop a board off the long side if the subject still reads, or split the project into clearly separate pieces.

Light cleanup in the editor

Some problems are easier to fix by hand than by re-running the wizard. After Pass 2, the editor’s drawing tools cover the small symptoms:

• A handful of stray beads in a flat area: pick the surrounding color and paint over them.
• A faint halo around the subject: erase or repaint the obvious cells. Do not chase every cell that disagrees with the background.
• A single jagged edge on text or a small feature: nudge one or two beads with the paint tool to make the shape read.

If you find yourself repainting more than a few dozen cells, go back to the wizard instead. Re-import, change one Advanced control, or change the framing. The editor is for finishing, not for redoing the conversion.

Final checks before you export

1. Run the squint test one more time. If a recent fix made the subject harder to read, undo it.
2. Open the Colors panel and confirm the color list matches what you can sort. Note any planned substitutions on paper so they are not improvised at the bead table.
3. Open the Boards panel and confirm board count and seam placement. Drop boards if the project is bigger than you can finish.
4. Wait for the header to say Saved locally. Keep the original source file too, so you can re-import with different settings later without finding the source again.
5. Open Export PDF. Choose Chart Reference or Exact-Size Tracing based on how you plan to build, then export. Source RetroBeads product RetroBeads PDF export dialog The current Export PDF dialog exposes Chart Reference and Exact-Size Tracing as the two export styles.

The PDF guide covers paper size, board-by-board layout, exact-size assembly, print scale, and how to keep one packet together.

Troubleshooting

• The squint test still fails after every fix. The subject does not have enough contrast to survive simplification at this bead count. Add boards on the long side, switch palette, or pick a different source.
• Confetti cleanup did not catch the strays. Confetti cleanup only removes very small isolated regions. Larger blobs of an unwanted color need Region merge or Majority filter in Photo mode, or a hand repaint in the editor.
• The color list is short but the chart still looks busy. The issue is probably dithering, not color count. Re-import with Dithering at None for pixel sources, or try a quieter dither in Photo mode.
• A seam keeps landing in a face no matter how I resize. Use the import wizard’s Rectangular select, Magic select, or Auto crop to recenter the subject before sizing the boards. Reframing the source is faster than nudging board counts.
• The chart needs more boards than I own. Drop boards on the long side until the subject still reads. If it does not read at the smaller size, the project is not the wrong size; it is the wrong source for this bead count.

What to do next

When the chart passes the pre-build pass:

• Sort beads against the Colors panel list and the planned substitutions.
• Open the PDF guide and export the packet you actually plan to use.
• If the project is large or has unavoidable board seams, read the tape method guide before you start placing beads.

The pre-build pass is short on purpose. Done before you sort beads or print, it catches most of the problems that turn into wasted beads, wasted printer paper, and a frustrating evening at the bead table.
