How about a ten-minute card? This card was relatively easy to make. I used the Big Angle Background stamp and stamped it onto white cardstock with black ink. I then used some watercolors in the shades of red, yellow, blue, and green to paint the background.
While I let the card front dry, I die-cut a basic rectangle frame die from my collection out of white cardstock three times. I like to layer the frames to give them some dimension, but you can certainly use foam tape for dimension instead of die-cutting it multiple times.
Then, with my Solid Sayings stamp set, I heat embossed that onto the card front with gold embossing powder and splattered white paint onto the card front.
When everything was nice and dry, I adhered the frame over the card front and adhered both pieces to a top folding card base.
Super simple! And, I hope you give it a try.
Have a wonderful day!
