I started out using acrylics because I lived in a small town with no craft store.
Walmart, however, offered the big bottles of cheap acrylic paint in a handful of colors.
So that is what I used.
Luckily, I seem to have a rainbow heart and the style that started out from a lack of resources stuck.
I use quite a few different kinds of acrylic paints now, but still paint the rainbow and avoid using much brown.
I later discovered Uni Posca paint pens and use them for detail work and my mandala components.
All prints are museum-quality matte paper, and printed after you order them- just for you.
I hope you find something that lights a little fire in your heart and brings color and joy to the space you choose to hang it!
