quilt

So, I went over to my aunt's house on Sat. and we started on Ethan's quilt. I have all this cool Sock monkey print fabric and I love how it is all coming together. The problem??? I can't sew a straight line and it is all driving me up the wall. My hubby says it adds character and I am on the verge of ripping out all the seams and starting over. UGH!!!! I want it to be perfect and it's not.
