Personally, I ordered it. Never in a gazillion years would I have figured it out on my own. I like instructions that are clear, concise and have easy to see pictures. This set of instructions fits the bill. I think if you are looking to make a "Raggy Bow" like this one, you will need the instructions to do it. JMO though.
I also have Wendy's instructions (hmmmmm...am I addicted??!!) and those are reat as well, but very different methods!
