Every once in a while I am working on a design when I realize I like exactly what I see in the tile in the editor. To get that as a design, I would need to pick a frame that matches the tile shape and then set the frame size to match the tile size.
Sometimes that design will inspire me to create a series of designs, like these snowflakes from last year, where each of the designs was a single tile. (Laser-cut from white posterboard. )
The new “Single Tile” as a frame shape feature makes it easier when you know you are working with one tile and takes care of setting the shape and size of the frame to match your tile.
Here you can see the design in the render area looks exactly like the design in the tile.
