A Book to Inspire
"Knit Tricks: Easy Shaping Techniques; 25 Stylish Projects from Simple Rectangles" by Rebecca Wat
This book is not for loom knitters, but the idea of working from rectangles is adaptable to the loom. The designer in this book uses different needles to shape many of the patterns, which does not always work on a loom.
Loom knitters do have different stitches that will increase or decrease our work while working on a loom that is not adjustable. The flat knit stitch will tighten and decrease loom stitch size, and the e-wrap knit will increase and loosen our stitches. 2 over 1 knitting will also decrease our stitches, while working on the same loom, so the ideas in this book are adaptable to a loom.
This is the scarf I was inspired to knit from the book:
It ties at the neck like a bow, and has 6 inches of bobble stitch rows at each end.
