Recently, I created the Ode to Spring Shawl pattern for distribution at KBLooms.com. It uses a knitting loom with 80 pegs. The sample used the Premium Round Loom Set, however, you can use any other knitting loom that it is similar in gauge.
You can find the pattern on their blog, as well as the video. In case you are not familiar with that blog, I decided to include it here too for your enjoyment.
