Sculpt one quarter — it mirrors into a full lantern. Drag the dots; tap a dot to toggle curve/corner. Green border = it tiles. Then Set.

Fill

Edit

The top tip rides the top edge; the side point rides the right edge — drag them along their edge only. Inner points move freely inside the box.

Nesting

Show nested neighbours
Live tessellation field
Tiles sit edge-to-edge; Grout weight paints an even seam between them — including the top/bottom tip junctions, which otherwise just touch at a point. Green = the edge nests evenly so the grout stays uniform all the way round. Snap reshapes a convex edge toward the nearest ogee that nests; a very bulgy edge can't share an edge cleanly, so the grout will vary — Snap evens it as far as the shape allows. Fill: Solid = filled tiles + grout channel; Outline = thin edge line; Grout = the seam drawn as the line.

Tile box

Lock aspect ratio
Sizes snap to ½-unit steps so the repeat always lands on clean full / half tiles. Lock aspect scales width & height together so resizing never distorts the shape.

Set & export

The file is always the repeating pattern built from your tile box. Repeat tile = one seamless unit (for POD / Canva). Page sizes fill that page with the same pattern at the same tile scale, so a bigger page fits more tiles — exactly how it prints. Resolution sets an A4 long edge in px; larger sheets scale up from there.
Single shape (one tile)
One lantern on its own. SVG is true vector (scales to any size, great for Cricut / Canva / large print); PNG keeps transparency; JPG is flat on the gap colour.
Colourway set

Canvas .

Sculpt the quarter.

Colour .

Set the two tile colours by hand, or import a scheme.

Manual colours

Import scheme

e.g. #1f3a63, #efe7d2 or a coolors.co/… URL (works with codes from Palette Hub). Paste 3+ and they become tappable chips — tap one to set it as the tile, Swap flips tile/gap. “From image” pulls the main colours.
