Do what interests you. To find what interests you, I would try a sampler quilt of blocks. I'd try to make the blocks the same size. It wouldn't have to be a pattern, you could just choose blocks from
www.quilterscache.com . I would try to stretch yourself by making some with squares or rectangles, some with triangles, the suggested kinds were good (HST, QST, flying geese), something with curves (like moon over mountain, drunkards path) Something with applique, and some hexies (grandmother's flower garden), The log cabin and orange peel are good.
