I have been working on artist cards. I like them because they are a great way to try out new ideas. They are small, so I don't feel like I am being wasteful if they don't turn out. I may even use some as business cards. I am having a hard time keeping them all the same size. Once I get that right, I might even sell them.
I have been mostly using them to try out watercolor card ideas. I am working on a lemon card and candle card right now.
Cards will hopefully be in my store soon.
