Repeat Crafter Me (of which I'm a huge fan) posted this picture and a link to her facebook page from Free Crochet Patterns showing the different sizes of blankets. I was so excited by the link that I saved all those images and some that I've collected on the internet and put them all into this one PDF. I have already printed out the three pages to keep with my printed patterns. I hope you find them helpful and useful!
