I would repair the really bad area's and finish it. My Mom crocheted and when she passed my 1/2 sister threw out all of her projects because they were not finished. Even after she was told I wanted them and all the yarns. I knew someone who could finish them. And we would all have the last projects she was making for each of us. I cherish the afghans she made for me.My son now 39 still has the ones she made him as a baby.They have been used and loved by all 6 of his babies. And eventually his Grand babies will enjoy the love that went into each stitch as well.
