I've compiled a list of my favorite supplies to help you build your watercolor kits. You will need a palette, paper, brushes, and paint. (A few projects also require a good pencil set and transfer paper). My favorite brand of watercolors is M. Graham, but I've also used paint from Windsor and Newton and from Utretch. This list includes brands that I use and trust, but feel free to try other products. Just make sure that you purchase only professional-quality watercolor paints. The pigments react differently than cheaper student sets and I promise that you will see a difference in your paintings if you use high quality supplies.
