Feathering in is a term commonly used to describe blending two or more things together seamlessly or gradually. The opposite of feathering in is rather straightforward: it is harshly juxtaposing two things, creating a sharp contrast or a clear divide. This can be accomplished in many ways, such as through hard lines, bold colors, or abrupt changes in texture. Antonyms for feathering in may include: contrasting, separating, dividing, detaching, or delineating. When used strategically, these techniques can be very effective in creating visual interest, depth, and drama in art, design, and other forms of creative expression.
