After creating your CutList Plus project on your computer, choose "Export for Mobile" from the File menu. This will save a copy of your project on your hard drive, specially formatted for your iPad. It will have a file extension of "icxp".

Attach the file you created in step 1 to an email message, and send it to yourself.

Switch to your iPad and get your email. The attachment will show up as an icon. Press and hold the document icon until a popup menu appears.

Choose "Open in CutList Plus" from the menu.
