I have tried duct tape and other substitutes, but nothing works like real feathers. Get some online or through the trading post. I mostly order precut feathers. Bamboo shafts will work- you'll need to dry them for months, learn to straighten them and you'll need to file and sand the nodes smooth like a dowel- some varities of bamboo are much better for this than others. like a bow, arrows are something that takes alot of time and it's own set of skills to learn. If you start "from scratch", an arrow can take many hours of exacting labor. For beginners, I reccomend buying a pre made shaft (not a dowel, but a shaft made for archery), and pre cut feathers. this will cost only a few bucks an arrow and will allow you to make a really nice arrow. once you see what that's like- graduate on to harvesting shafts, and splitting your own feathers.
