I seem to recall a couple of sites out there that sell whole-leaf tobacco for cigars (as well as pipe, cigarettes, etc.). The only one i remember off the top of my head is http://www.leafonly.com/ Michael may know of some other sources as well.
As Kip says below, LeafOnly.com is very good, and is where I get most of my filler leaf, as well Connecticut shade wrapper. I also use OtoaoCigars.com for two kinds of wrapper (Ecuador dark and yellow shades) as well as some binder and other filler. Wide variety of countries of origin and strengths (seco, viso, lijero, etc). I have some videos up on YouTube that show what I do with storing my leaf and then humidifying them before rolling. Search videos by stewmuse. Good luck!
These videos and some other rolling related stuff is in an iBook I put out last year.
"Cigars @ Home" on the Apple iBookstore.
Holy cow! You could teach us about hand rolled cigars.
I have a bunch of tobacco seedlings sprouting with picture attached.
Nice. I'll probably plant what I can in my back yard and sell the others to my friends at The Party Source, Newport KY
