We actually missed the original Gertie's New Book for Better Sewing back in 2012, which was a guide to creating your very own mid-20th century clothing and the techniques required. Like the blog that inspired it, the book was a hit – so much so that a second volume is on the way. That is Gertie Sews Vintage Casual: A Modern Guide to Sportswear Styles of the 1940s and 1950s by Gretchen Hirsch.
