Throw away your to-do list and go play on Repper (discovered via The Shopping Sherpa). Repper lets you create patterns from uploaded images; there's a demo version to try for free.
Once I got over the glorious kaleidoscopic dizziness (that took a while - pictures of flowers! Whee!) I started finding that the simplest source images gave the most interesting results. These are all from a few comic frames.
Repper lets you save the tiles as well as the images, and that's where I got really hooked. Digitally-created patterns can look bit too clickety-click. But cutting these as lino blocks, and overprinting colours....
I usually start designs with a general sense of what I want them to feel like: 70s hotel linen, shwe-shwe, great-auntie's curtains. This turns that process upside-down.
Yet in the end it doesn't feel terribly different from using graph paper and a compass (yes, those are my favourite toys for repeats); just very much faster.
