Nicpro Miniature Paint Brushes Dry Brush - 21PCS Model Paint Brush Set with Cloth Roll for Acrylic Oil Watercolor, Detail Paint Brush Drybrush for Model, Miniature Painting, Paint by Numbers, Craft

For brushes, I’d look at miniature painting brushes rather than paint-by-numbers brushes. Search terms like “miniature detail brush”, “spotter brush” and “short bristle round brush” might get you closer to what you’re after. A lot of model painters prefer shorter bristles because they give more control. I bought this Nicpro 21 piece set from Amazon: https://www.amazon.co.uk/dp/B0DJ2ZNRPQ?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 An angled drawing board or small tabletop easel can also make a surprising difference when working on smaller kits. It lets you move the canvas around more easily without hunching over it. There’s absolutely nothing wrong with preferring smaller kits. I’d rather finish ten small paintings I enjoyed than force my way through one giant canvas I wasn’t having fun with.
