One of my grafting experiments.
In April 2010 I grafted a piece of an epiphyllum on a Myrtillocactus. It
has not died yet, but there has not been much growth either except for a
tiny sprout in spring last year, which broke off (due to my clumsiness
. But there are small buds again this year at the uppermost eyes at
both sides. The scion at the right of the stock has grown last year.

Cool, I have an orchid cactus that looks something like that. How is
it done, the grafting I mean?
