COLOURLovers is a site dedicated to creating and sharing colors, palettes, and patterns. The functionality is terrific and it just got better today with the release of their version 4. Amongst their new offerings is Seamless Studio, a tool for creating seamless patterns online. Now this isn’t a fully featured pattern generator; you’re limited to playing with a couple dozen shapes and lines, but it’s still fun to see patterns come to life right before your eyes and experience the endless possibilities even with this finite number of motifs.
Shapes and lines can be resized, rotated, copied, and layered. You work in grays at this stage (the live layer is pink) then save your pattern. It is then released into the community, and anyone can color it. If you’re curious about copyright info, read this.
And it’s a good thing we’re discussing block repeats this week because that’s what Seamless Studio does; but you can create a full- or half-drop by manually dropping a motif and grouping it with the original, as below. The only thing I don’t like is that there’s no tool for aligning your motifs; you have to eyeball everything.
Oh and did I mention? COLOURLovers is partnered with Spoonflower, so the patterns you create can be printed onto fabric.
