To curve your text, simply type in the word or phrase you need to curve and choose what level of curvature you want, from -10 to +10 then click on add text.
A positive curvature (+1 to +10) curves the text upwards to varying scales:
A negative curvature (-1 to -10) curves the text upwards to varying scales
You can always edit the curvature anytime by clicking on the text box and the pencil icon.
TIP: Matching the curvature to the topper border
If you're trying to match the curvature to the topper border, try resizing the text also to get different degrees of curvature. A future release will allow for even more incremental options.
The scale of curvature selected is only displayed after clicking the 'add text' button. Any other edits can be previewed in the top preview window.
