What I would do is take the finished blocks and small pieces of fabric that have already been cut out and set them aside as the beginnings of a "stash". The pattern can be the start of your pattern collection of "someday" quilts.
For the fabric that is left, I would probably do a baby quilt in a rail fence pattern. That would give you strip piecing experience. The pattern is an easy one that doesn't require matching seams; you just have to make sure your blocks are square before sewing them together. You can always buy a little more fabric to add to what you have if you need another color, a contrast fabric to spark up the quilt or for borders, etc.
Remember that quilting started out with women using leftover bits of fabric from everywhere. Some of the most wonderful quilts I have seen were very spontaneous, with fabrics sewn together every which way -- no need for an exact pattern, exact cutting or sewing, precision.
You can abandon the pattern and use the fabric for a different creation.
