I'm glad you found what you need. I know there are a lot of loom knitters and I'm surprised there isn't more help specific to loom knitting. You need a site that is just for loom knitters to ask questions and help each other figure things out. The most important thing is that you can do something you enjoy and produce a finished item that you're glad to have made and will be useful. Even though we aren't loom knitters, I'm sure that if you'd like to share a photo when you're done that we'd love to see it. Best of luck and enjoy!
