With the help of books and the internet, I've been teaching myself how to weave bands on an inkle loom. Here are some books I've found very helpful. I've only been weaving bands for a couple months so this is not an exhaustive list. However, everything I have listed is in English and currently available (February 2016).
My go-to book for patterns and instructions is Anne Dixon's book The Weaver's Inkle Pattern Directory. She has a variety of patterns from plain weave, Baltic weave, South American Pebble weave, Monk's weave and lettering just to list part of the content. She has excellent diagrams and explanations of how to warp the loom (putting the long threads on the loom which are the foundation for the weaving design).
Susan Foulkes has 3 self-published band weaving books for sale on Blurb.com. If you own a tablet, purchasing the e-books is a great way to get the information at a lower cost. Normally I prefer paper books, but I've been really happy with her books in this digital format. Susan excels at explaining the weaving terms for a total novice. I recommend the The Art of Simple Band Weaving if you are new to band weaving. As a next step, her Sami pick-up weaving books are excellent. Susan also has a number of excellent YouTube videos. The inkle loom is only one way to weave a band. A backstrap with a rigid heddle is probably the most commonly used method for band weaving (shown with the woman weaving on the book cover above). Here's a link to Susan's video showing Five Ways of Weaving Narrow Bands.
Heather Torgenrud's Norwegian Pick-Up Bandweaving book is a beautiful book. She discusses the history of band weaving in Norway. Her book has beautiful photos of Norwegian bands, costumes and tools used for weaving. She has created charts of patterns for the historic bands. For one of the collections, there is a photo of a band and a chart number for the patterns which are grouped together further on in the book. Any reader will enjoy the history and photos in this book. She does give step by step instructions for setting up the warp and weaving the patterns. An confident beginner will do well with this book.
The Braid Society based in the UK has lots of resources. Here is list of the books the Braid Society sells. (I'm still a novice and not sure where I'm going with this craft, so I'm not a member).
