Some of my favorite visual artists are masters and manipulators of pattern. See what you think of these. TO see more of their work quickly, do a Google Image Search including the artist name and the medium (i.e. Matisse paintings). PS these are intentionally NOT quilt or fiber artists. It's important to look out!
You'll notice that the last few of these artists were represented with art work on the site Artsy.net. This site is a great place for inspiration. You can search by artist, genre, time period or a general keyword. Really good artist date time!
