it looks to me like you may have cut off the seam allowances at the points. are you using EQ? which block type did you print? personally, i would choose Templates. if you are doing English paper piecing, you have to have the seam allowance all the way around the piece and then sew to just the 1/4" seam allowance mark, leaving the seam allowances for the points 'free'. then, as misspriss had said, sew together in pairs, then the pairs together, then the two halves. i hope this helps
