I'm enjoying the quick and easy, mostly because with me they are NOT quick and easy - generally something goes wrong during my execution (run out of thread, material, time, patience, machine goes down, etc)!!
Practice makes perfect. Yet the quilts I've made that were more complex actually tend to stick in my memory a lot more (maybe because of the time they took to make them). I love the bright bold colors put into traditional blocks, with some kind of scrappy twist to the pattern. Love it!
