Okay... got it! The patterns are from "Make It Yourself: The Complete Step-by-Step Library of Needlework and Crafts" published in the 70s by Phoebus Publishing. Here's what they look like: http://www.amazon.com/Make-Yourself-step-step-needlework/dp/B00005WC40
There are multiple volumes (I have 1-3), and they contain step-by-step instructions for crocheting, knitting, macrame, and all sort of crafts, as well as four sewing patterns per book. The patterns are numbered consecutively.... Volume 1 has patterns 1-4, Volume 2 has 5-8, etc. So your pattern #5 is from Volume 2, and 13 is from Volume 4.
The pattern sheets themselves contain all of the information needed to make the clothes. The book has pictures of finished product, in hilarious 79s fabrics, and also pages of instructions on certain techniques... working with interfacing, how to make a gathered sleeve, etc. I'd be happy to copy the pages out of Volume 2 and mail or fax them to you, if that will help. Also, I could try to get by the thrift store where I bought mine to see if they have Volume 4.
