Here are two cards that I made recently. They are handcut out of black paper with coloured paper glued behind the paper cut.
I love the shadows!
I steered away from my usual rainbow colour choice to warm colours for this card, because I thought my aunt would like it more. Some of the colours are really similar. Each section of the mandala is a different coloured paper from the other sections, but you can’t tell, which is annoying because I cut out all the sections separately. I just need to remember to not use such similar colours next time.
Here’s the rainbow card, because, when in doubt, make it rainbow. I think I prefer this one because the colours are obviously all different, and because it’s rainbow. You can’t go wrong with rainbow.
