Textile designers draw ideas for patterns and designs on paper or by using computer software programs, such as Artlandia SymmetryWorks, a plug-in for Adobe Illustrator, Bontex, textile CAD software, Evolution Textile Design Software, or LECTRA. There are numerous types of repeated patterns; the most common, half drop and straight. Sometimes, the same design is produced in a number of different colors, which are called colorways. Once a pattern or design is complete, the process shifts to picking the fabric(s) on which to print or weave the pattern.
