Bests & Worsts Reviews from Amazon

There is something wrong when one has to do the proofreading before following a pattern. Does anybody proofread before publishing, especially when math is so crucial to pattern writing. Much to my major disappointment, when I finally pull the book out to sew a skirt with much anticipation and expectation after buying a pretty piece of fabric at a very pretty price and proceed in following the directions to make a semi-circular wrap-skirt, and having cut accordingly, I discover that the math is completely off. N.B. Do not divide the final waistline measurement by 6. This is incorrect information. Yeah, I didn't end up with the skirt I had in mind... and I don't give praises for books that give the wrong information and can cause one much grief and an emptier wallet than initially planned.
