I started off by stamping the sentiment first and embossed it in white. I used washi tape to keep the sides of the card clean when I do my stamping to make a nice frame.
I used a brown ink to stamp the frames first before filling the frames with some bugs and leaves.
After that, I used my copics to colour the images. It's pretty easy however, you should be light handed with it. And remember that the copic colours will not come out as vibrant as it would be if you used it on white paper.
Hope you'll give this a try!
