everything I personally use to paint and make art. honestly I don't have too many things I use, so this is a smaller list.
these are the easiest way to begin oil painting, just needing water and a good artist soap to clean up instead of turpentine and mineral spirits.
Winsor & Newton Artisan Water Mixable Oil Paints
the best heavy body professional grade acrylic paints there are. these have the least amount of shrinkage and lack of luster in mixing.
Golden Artist Acrylic Heavy Body Paints
oil paper is a thicker paper that will not wilt under the weight of oil paint, and works great for sketching or more casual works.
Arches Oil Paper Pads - 9" x 12", 12 Sheets
the absolute best brush cleaner and preserver for all brushes. this cleans oil, oil paint, acrylic paint, and tough pigments like phthalo.
The Masters Brush Cleaner and Preserver
my favorite disposable palette. the grey background helps to make colors as they are mixed appear true to tone, as opposed to being washed out by a white background or too bright by a black background.
New Wave Grey Pad Disposable Palettes
glass palettes provide a lot of durability in cleaning and usage without flaking or clinging that comes with plastic palettes. these are a really good investment that will last a long time if it is taken care of properly.
New Wave Posh Glass Tabletop Palettes
I personally use fine liner pens for sketching and finalizing sketches, and they work as a good alternative to office pens.
Winsor & Newton Fineliners and Sets
these are the best synthetic brushes for firm bristles that can work for both acrylic and oil.
Princeton Catalyst Polytip Bristle Brushes and Sets
palette knives are helpful for mixing paint and applying impasto layers of paint, and these have a nice finish that makes the paint on the knife more visible.
