A classic old type pattern of stars, etc is great for homespuns. If you wish the fabric to look old people usually sew it before washing the fabric. Then once done, you wash the quilt and the fabric shrinks and looks all weathered. Very effective if it's the look you want. Also since homespuns ravel more I would use a wider seam allowance than 1/4 inch for piecing.
Have fun.
