Know your pegboard first
The whole plan depends on the board. The standard square pegboard is a 29x29 grid, and mini boards are around 14x14. Patterns are usually built as one board, a 2x2 arrangement (58x58) or a 3x3 (87x87), because the boards physically interlock. Decide the board count before converting anything - retro-fitting a pattern to a different grid means redoing the conversion and the bead count.
- 1 board: 29x29 - small sprites, badges, keyrings
- 2x2 boards: 58x58 - most character portraits and logos
- 3x3 boards: 87x87 - detailed art and photo conversions
Convert the image to the right grid
Set the pixel size so the output is close to your target bead count, then crop tightly around the subject - every pixel you give to empty background is a bead you do not need to place. For a 58x58 pattern from a square photo, that means a 58 pixel wide result; increase the block size until the width matches, then adjust the crop rather than the grid so the aspect ratio still fits.
Reduce the palette to beads you own
This is where most first attempts go wrong. A converter will happily produce 64 colours; a real project wants 12-24, because every extra colour means buying and sorting it, and each colour change is a break in the flow of placing beads. Set the colour count to the number of bead colours in your stash or the set you plan to buy, then map the output colours to the nearest real bead colour by eye.
Count beads before you start
- Total beads = grid width x grid height. A 58x58 pattern needs up to 3,364 beads.
- The maximum is rarely the real number - background pixels you leave empty do not count.
- Count per colour by working row by row, or use the pattern as a checklist and tick as you go.
- Buy 10-20% extra of the colours that dominate, because a mixed bag rarely contains an even distribution.
- Order the colours before starting the project; stopping mid-board is the usual reason a pattern never gets finished.
Ironing and finishing
Cover the finished beads with ironing paper and iron in small circles on medium heat until the beads fuse - a light fuse keeps the individual bead look, a full fuse gives a smooth flat surface. Iron both sides for a sturdy piece, then place a heavy book on it while it cools so it does not warp. If the pattern spans multiple boards, fuse the sections one at a time and join them at the end, or the whole piece will shift as you iron it.
Where perler bead patterns come from
- Game sprites: the original pixel art is already a perfect bead grid; scale it to 29x29 or 58x58.
- Photos: convert and raise the colour count until faces are readable, then cut the palette back for purchasable colours.
- Existing cross-stitch charts: the same grid, often already limited to a manageable palette.
- Logo and icon art: flat shapes convert cleanly and need very few colours.
