I like scrap quilt that have a unifying background color and common block.
Currently swimming in pink scraps...because I hate pink. So it's the last color I reach for...ever. I need to practice my flying geese so I'm using the pink with a variety of grey's as my background and making stars. What is surprising me is how much I am liking the resultant blocks. I'm using an 8" finish because it seems to make best use of the WOFs I have leftovers.
So that's my suggestion. Find a background you like (white is easy) make a common block with them (hsts are easy but maybe you think snowballs are the *bomb*). Just something you can live with and keep building. When you feel like you have enough...
