LED strips that come in rolls are convenient for, well, making illuminated strips. If you want to cover a wider area, you can lay rows, but then you've got to solder the connections for each. To save time and provide design flexibility for these types of applications, a Denver-based company called Evo-Lite makes Auragami, a roughly 9" x 20" sheet that you can cut to size.

The company reckons Auragami will be helpful in the following situtations:

- Final dimensions are not known or likely to change

- Folding and/or cutting would save time during installation

- Curved surfaces or mixed sizes and shapes are involved

- Multiple planes need to be backlit

- A low clearance solution--as little as 3/8" (9.5mm) or more of space behind the translucent material--is needed

- Dry, damp, or wet location use
