i was going to make some big write-up thing about this later, but my personal favorite pattern website is colourlovers!
a lot of people use colourlovers for their awesome palettes (as they should, because they’re perfect), but colourlovers actually has a huge variety of patterns to choose from, as well! you can sort through the most popular ones, and when you click to make them bigger, you can even color them however you want (or keep them the way they were originally created!).
there are a ton of patterns that you can create and color, and all of them are seamless, so you don’t have to worry about that.
all you have to do when you get to the pattern you like is click here:
and it’ll open up in a new window for you to save, and then you’re good to go!
the patterns are really unique, and there are so many to choose from. in my opinion, it’s always been a much better option than patterncooler (and they’re not charging you, like, five bucks for any of it).
