Getting Started With Watercolor Without Wasting Money
I've been doing this long enough to know that most people blow through their budget on supplies they don't actually need. I once watched a guy spend nearly $400 on brushes, a canvas pad, and a fancy palette before he'd even put brush to paper once. He returned everything except the brushes and came back asking what the minimum viable setup was. That's the baseline I'm working from here. The Top 10 Watercolor Checklist isn't about having the best gear. It's about not making the same mistakes I made for the first three years of painting, which mostly involved buying cheap paper and wondering why my colors turned into muddy gray soup. Paper is the thing people get wrong most often. A 140lb cold-pressed sheet from a major brand will cost you about $3 to $5 per sheet if you buy it in a pad. The sketchbooks at the craft store for $8? They're 90lb cotton blend at best and they buckle, warp, and pill under even light washes. I learned this the hard way on a landscape piece where the paper buckled so badly during a wet-on-wet gradient that the whole composition shifted halfway through drying. I ended up cutting the warped section out and patching it with gesso, which defeated the whole point of starting fresh.
Top 10 Watercolor Checklist
1. Paper weight and sizing. Go for 140lb (300gsm) cold-pressed cotton paper. Not hot-pressed, not inkjet paper, not "watercolor paper" from the art supply section that has no weight listed on the cover. Cotton is the standard because it absorbs pigment differently than wood pulp. You get more control over washes and less ghosting when you lift color. A single pad of Good Paper or Arches 140lb cold press runs about $25 to $35 and lasts roughly 40 to 50 paintings if you're working at a modest size like 9x12 inches. 2. Brush selection. Start with three: a size 8 round, a size 10 round, and a size 12 flat. That's it. More brushes than that in the beginning just means more cleaning and more fiddling. I used to own about 18 brushes and I couldn't tell you what half of them were used for anymore. The round is your workhorse for detail and controlled washes. The flat handles broad strokes and building up areas of tone quickly. If you're doing anything beyond basic exercises, the size 10 round covers most of your needs. 3. Pigments over tubes labeled "student grade." This is where the money gets tricky. Student-grade tubes are cheaper but they use less pigment and more filler. A wash from a student-grade phthalo blue looks vibrant until you add a second color on top, then it turns dull and chalky because there's not enough actual pigment to build layers. I switched to professional-grade for my main colors about two years in and it changed everything. Winsor & Newton Professional, Daniel Smith, or Schmincke all have strong core sets. The downside is a single tube of professional-grade paint costs $8 to $14, compared to $2 to $3 for student grade. But a tube of professional-grade paint typically lasts twice as long because you're not wasting volume on filler.
4. Palette setup. A white ceramic plate works fine for mixing. A proper palette with recessed wells is better because it prevents pigment from rolling off the surface when you tilt the palette to load your brush. The $3 plastic palettes from the craft store crack within a month and the wells are too shallow for meaningful mixing. Get something with at least 12 wells and a flat mixing area that's four or five inches wide. 5. Water containers. Two containers, not one. One for clean water, one for rinsing your brush. If you use a single jar, you're diluting your clean water with every dip, and your washes look streaky because you're dragging dirty water into clean areas. This is the single most common error I see in beginner work. I still do it when I'm rushed, which is how I ended up with a sky that looked more like a bruise than anything atmospheric. 6. Masking fluid for areas. If you're doing anything with negative space or hard edges, masking fluid is necessary. Latex-based masking fluid like Henry's or Winsor & Newton works well. Apply it with a separate brush or a silicone tool, let it dry completely before painting over it, and remove it after the paint is fully dry. The edge case I ran into: masking fluid left on paper for more than 24 hours can bond into the paper fibers and tear the surface when you try to peel it off. I discovered this on a piece where I let a masked area sit overnight and when I peeled it off the next morning, a thin layer of paper came with it. I had to patch it with a scrap of the same paper and re-wet the area gently to blend the repair. Not a disaster, but a reminder to time your masking fluid application.

7. Tape for mounting paper. Painter's tape, 1-inch width, applied to all four edges of your paper before you wet it. This keeps the paper flat while you work and gives you a clean border when you peel it off after drying. Cheap tape leaves residue. I switched to 3M Frog Tape about a year ago and it comes off cleanly every time. The cost difference is negligible but the frustration of trying to scrape dried tape adhesive off a finished piece is not. 8. Palette knife for mixing. A small stainless steel knife lets you pick up precise amounts of pigment from the tube and mix without contaminating your clean water. It also helps you test color intensity on a scrap piece of paper before committing to the painting. I used to mix directly in the pan and it took me twice as long to get consistent saturation across multiple washes. A knife cuts that in half. 9. Sponge. A small natural sea sponge or a synthetic equivalent for lifting color, softening edges, and creating texture. The sponge is also useful for pressing out puddles before they dry and become rings. I keep a cheap kitchen sponge in a jar of water on my desk specifically for blotting. It's not fancy but it saves more paintings than anything else in the setup.
10. A drying rack or flat surface. Your paintings need to dry flat and undisturbed. Leaning them against a wall causes the pigment to migrate toward the bottom edge as the water drains, leaving uneven saturation. A simple wire cooling rack from the hardware store works perfectly. Lay your paintings face-up on it and leave them for at least 12 hours before varnishing or framing. I used to stack them in a clipboard folder while they dried and the bottom painting would always have a slightly different sheen than the top one because the moisture couldn't escape evenly. There are some real limitations to this approach that nobody talks about. The biggest one is that professional-grade paints require a different technique than student-grade. Because they're more concentrated, they dry darker than they look in the tube. A wash that appears light pink in the pan might dry into a deep rose. You have to learn to overestimate your water-to-pigment ratio, usually by about 15 to 20 percent compared to what you'd use with student paint. The second limitation is that this checklist doesn't solve the problem of painting speed. Watercolor demands quick decisions. If you're the type who wants to spend an hour planning before touching the paper, you'll struggle with the medium. The workarounds are either to practice your composition as a graphite sketch first, or to accept that the first layer is essentially a guide and you'll adjust as you go. The total cost to build this setup from scratch, assuming you already have a basic desk and some household items, runs about $120 to $180. That covers paper, three brushes, a palette, two water containers, masking fluid, tape, a knife, a sponge, and a drying rack. Compared to the $400 I saw that guy spend, it's modest. Compared to buying everything in the cheapest tier, it lasts significantly longer because the paper doesn't fail mid-painting and the pigment doesn't turn to dust after two washes.
If you find yourself hitting a wall with the paper buckling despite using 140lb cotton, you're probably working too wet for that particular brand. Switch to a heavyweight 300gsm pad or pre-stretch your paper by taping it down and applying a light wash with clean water before your actual painting. The pre-stretch step adds about ten minutes to your process but it eliminates the warping issue entirely for most standard techniques.
