How to print PDF patterns at home
Don't go to the copy shop. Tile your patterns in 3 simple steps.
Upload large format PDF
Drag and drop your A0, A1, or large-format PDF/DXF pattern. We accept files from Etsy, Burda, specialized CAD software, and all indie designers.
Convert to A4, A3, Letter, or Tabloid
We automatically split and tile your large pattern into perfectly aligned pages that fit your standard home printer — A4/A3 for international users, US Letter/Tabloid for US users.
Print, tape, and sew
Download your tiled PDF. It comes with page numbers, cut lines, and a free assembly diagram so you can tape it together in minutes.
Built for sewers who hate taping (but have to)
We make the assembly process as painless as possible with smart features.
Scale verification square
Every conversion includes a test square. Print page 1, measure it, and guarantee your size is 100% accurate before printing the rest.
Free assembly guide
No more puzzle solving. We generate a custom "map" showing you exactly how your tiled pages fit together to recreate the full pattern.
Professional tiling
Our algorithm handles overlaps and cut lines with sub-millimeter precision, ensuring your seam allowances remain perfect.
No subscription trap
