You can now shop all of my favorite painting supplies. The supplies do not make the artist, but who doesn't love finding new art supplies to try out, right? Throughout my journey, I have discovered that painting supplies, specifically watercolors, happen to be a supply that not investing in better quality paper at the very least can indeed have a negative effect on your end result. So, when it comes to watercolors specifically, my advice would be to first upgrade your paper before upgrading your paints.
