With an incredibly huge thanks to Cardsmith member, Cryptonight, we now have the resources for split-border hybrid frames for the M15 card editor. As of tonight, Premium account members have early access to use and create cards with the new frames. After the next set of updates, the new frames will be made available to everyone.

To select a two-color frame, use the Advanced Card Color dropdown, and scroll to the new Hybrid Frames options.

We've got some additional frames in the works and will return with a full update once those have been processed and added.
