Directions are too hard to explain so I will refer you to Rachel Tessman's video from a year ago.  Even though I thought it was easier for  you to see the video, it isn't a hard card to make.  This was definitely a new fold and way to use dsp.  

I actually made a third one but wasn't happy with it and decided not to share.  The main thing is to have dsp that has coordinating designs on both sides.  Give it a try.

Thank you for coming by today!
