There should be a 1/4" seam allowance on each side to keep the points crisp. What size is your block measuring? I am not sure you can do anything with this block because it is to small, or other pieces were made with a wider 1/4" seam allowance. You can use it for a learning curve though. I am not sure if taking it all apart will give you what you want is you use a more scant 1/4" seam allowance. No harm in trying. This is a beautiful block and you will get it right It is evident you are on the right track.
