elizabeth lee is so awesome! I have almost all their patterns and have made several slings, they are really easy. And the sling pattern also comes with a pattern for making a waterbottle carrier, tote bag, fanny pack, and child doll sling with it (I've made the fanny pack). They also have great nursing clothing patterns, with really clear directions for beginners, their latest is a mamacoat in polar fleece, it's my next project. I have made many of their things, my nursing dress is my favorite. Excellent service too, and sewing contests.
