Nice star.
It seems like you might have your points cut off when you will put
your blocks together or you will have very narrow seams which may
cause more problems later. If I were you I would redo it.
I don't like to use the term scant 1/4". I think it confuses a lot of people
and it will vary depending on fabric and thread used. So it's easier to just
sew three strips of fabric 1 1/2" wide, press and check if you get the perfect
1/4". If not adjust your needle a tad and test again. Hope this helps.
