Sometimes little goofs actually enhance the finished product rather than ruin them. The hardest cuts are the first couple that being cutting the hides apart for the front/back & sleeves. The rest are much easier. I've actually made a ragged cut maybe somewhere around one of the sides or right above one of the breast areas just to have a seam to sew. Sew it together and pull it tight to pucker it and after you're done sewing you can pull it apart and flatten the puckers. It can add something to the look.
