HOW TO: ADOBE ILLUSTRATOR
Illustrator is a vector-based program used by designers and artists to create everthing from stunning web and mobile graphics to logos, icons, book illustrations, product packaging, and billboards.
Vectors, as opposed to rasters which are made of pixels, are infinitely editable and scalable. Vectors, as the name would suggest, are made of vectors (or lines) and unlike rasters will not become "fuzzy" or blurry when scaled.
Illustrator is a great program to transform simple shapes, colors, and text into sophisticated logos and colorful designs.
