I'm pretty sure you can get the Grafting Tool and Buddy Tape off E-bay or Amazon. I got my Buddy tape from a guy in the forum I linked about (he did a bulk purchase, save a little money that way).
Yes, I will probably do more than 4 varieties. I didn't realize how successful it would be (I've seen a lot of posts about trouble fig grafting) so I did a lot of the same variety to make sure it was successful.
7 panache grafts (4 fully leafed, 2 pushing buds, one idle)
6 Vdb grafts (5 fulling leafed, 1 pushing buds, one I knocked off tree by accident!)
As far was when to graft, I waited until the tree was more than pushing, and actually had put some leaves out, then cut those first leaves off and grafted below them. The scions were dormant from the fridge when I put them on. Then I made sure to pinch off anymore of mother's trees pushing buds/leaves so that all the sap/energy would go to the grafts.
Hope this will encourage others to try. My goal was to have fun with it. People can come over and see a variegated fig, a purple fig, and a green fig all on the same tree! (actually the two green figs have different color centers). Maybe I need to add a yellow or something next year...
