@Reinikka was offering up a bunch of little mini hearts over in the Use It or Lose It thread and this idea immediately popped into my head as soon as I saw them.
Wow! This came out stunning! Your method for keeping all the hearts straight is so smart and I agree that framing this took it to the next level! I love that all the hearts are different, it adds a really fun scrappy element to the work.
I went with random, the only thing I did watch out for was trying not to get hearts from the same paper too close to each other. Luckily there was a huge variety in the hearts so I only had to swap a couple around.
I make the projects with the frames in mind. I knew I wanted to make some wall art so I bought a few extra frames the last time I was at IKEA. For this one I picked a frame, measured the inside of the mat, then laid out the hearts to fill the opening.
