I did some in red and some in blue, since I have boy/girl mix brother and sister and didn't want the same exact card for both and changing up the colors was all I was up for

There seems to be a little bug in radial gradients. When you open the file the radial gradient is not visible in the heart, but if you select the heart and do color/gradient you'll see it and all you have to do is click on the radial gradient image and it pops right in. I have reported the bug to CraftEdge as I found it in both ecal2 and scal4.
Happy day.
