If you only need to arc one piece of text, you can start from the Letter Stencil Maker. Once you have your text, click the blue Customize & Print button.

On the next page, click Customize then Arc.

If you want a complete circular curve, enter 360 degrees.

If you want to arc separate pieces of text differently, you can use the Designer: (Requires the Designer or Pro version of Rapid Resizer.)

1. Click the Add Text button near the lower left.
2. Enter an arch value in degrees. Enter a negative value to arc upwards.
3. Once the text is added, click and drag on it (with the Select tool) to position and size it.
4. Go back to step 1 for each piece of text.
5. When you're done, click the Print button.
