After learning the very basics and not sewing for years I wanted to get back into little projects and needed a good reference book with info. Here is a book I bought and has been very helpful with all the terminology and sewing notions. School of Sewing by Shea Henderson. It comes with easy projects to build skills and wonderful images and explanation. School of Sewing by Shea Henderson
The finished size once you've squared them up should be 4 1/2" for the pattern I followed. The class I took had us get this book: School of Sewing: Learn it, Teach it, Sew Together https://www.amazon.com/dp/1940655021/ref=cm_sw_r_awd_hsmcvb0EE2ZPP She's a local Kansas Citian like myself, so I had to share the love. :D it's a great book and has really great beginning sewing projects and the last project goes through the quilt I made, in case you were interested. :)
