I'd pick it out back to the white star blocks. The sashing looks kind of crappy and more recent than the blocks, which tells you the blocks sat around for probably someone's lifetime and someone else decided to finish the top. You can put the inner blocks back together and don't worry that their points don't match...all part of the charm! That yellow looks like it's going to ravel out pretty quickly and be problematic, so if you don't want to change it you should reinforce it somehow, or quilt really well along it's seam lines. The basic blocks are charming, it's just sashed and assembled badly. You definitely got your dollar's worth!
