I like to use the Umbria Tip-Dyed series brushes when glazing with oil colors or where a softer touch is needed. What I like most about this line is the way the brushes hold their sharp tip and edges even when using solvents or mediums. When I need a clean, controlled, sharp edge in a painting, such as the edge of a building, this is the brush I reach for. When I scumble on textures in rocks, old buildings, and evergreen trees, this brush provides the lightest touch and just drops the paint along the texture of the canvas, fleshing out the object. I also like the Velvetouch handles — they feel secure in my hand and are a pleasure to hold.
