The Alphabet Series is a part of Drew Europeo's 365 Days Projects. She wonderfully mixes lines, shapes and color to create different letters of the alphabet. Each one has a unique look but fits well inside the series. She also has a project that explores lines and geometry and a project that explores pen and markers as part of the 365 Days Projects. You can check those out and other non-commercial works at Grafikas. She also has a site for commercial work, a Twitter, and a Facebook accounts.
