Draw your idea onto a blank SIBUBU. What you draw here becomes a true-to-scale template, and you can preview how it looks wrapped around the actual cup. Print it out, cut it, paint it onto a real cup with an off-the-shelf raku-yaki marker, and bake it in your home oven — and it becomes a one-of-a-kind SIBUBU.
Draw freely, or place an image, onto the area that wraps around the white porcelain cup (including the wavy skirt at the bottom).
Drag a placed image to move it. Click "Place here" to commit it to the drawing.
Converts your drawing into a fan shape, calculated precisely from template measurements taken by test-fitting against the real cup (top edge 214mm / bottom edge 262mm / side 68mm). It's the true shape that wraps around the real cup without stretching the paper.

In the print dialog, choose "Actual size / 100%" and turn off "Fit to page." It prints at true scale — cut it out and wrap it straight onto the cup. If it prints in portrait, manually change "Orientation" to "Landscape" in the print dialog.
Check how it looks wrapped around the actual cup, rotating it to see all sides (this is a simplified on-screen preview — use the fan template from Step 2 for printing and cutting).
Your drawing from Step 1 will appear here automatically
Cut out the printed template, hold it against the actual white SIBUBU cup to check the placement, then paint directly onto the cup with an off-the-shelf raku-yaki marker.
Raku-yaki markers are available at craft and art-supply stores or online.
