I watched a class on piecing and she used a small piece of wash away stablizer at the end of her pieces especially ones that needed a sharp point when pressed open to help stablize the end of the fabric and avoid the movement of the 1/4 line that happens at the end. It washes away when the quilt is washed. And the points on stars are perfect and won't tear open. She also mentioned that some 1/4 feet are not 1/4" when you sew with them so you need to measure after you sew to check your foot. I tried this tip on a star border and it worked great.
