A 5x7 inch masterboard gives you 4 ATC cards

You will make 1 masterboard that is 5x7 inches, go 1 step further now and add more like stencils or rubber stamps, or both, then cut it so you end up with 4 ATC's that are 3.5 x 2.5 inches. At this point use some additional embellishments, remember they are a set you send to 1 partner

I took this idea from Mararet Miller. Margaret Miller does a video about this process on YouTube, if you want to see someone do it beautifully.

That's it

Have fun make sure to include appropriate info on cards
