Thought I would try and buy some bamboo from a supplier of garden supplies and ect. I ordered the 3' length 25 per package hoping to get at least 6 good ones as the price was only about $10.00 including shipping. Well I was shocked to receive the package and it included 25 fairly straight shafts that measured from 7mm on one end to 10mm on the other. I haven't check the spine yet but I believe at least 80% are great for my needs and the rest for my grandson's bow. I ordered them from Amazon.com under bamboo stakes. They had 3,4,5&6'lengths. Hope this supplier can help someone else with their bamboo needs for cheap.
