Welcome! One way would be to put a "Looking for variagated Algerian ivy" post on our classifieds forum here:

Another way would be to send a treemail to the people who have this plant. You could ask if they'd be willing to sell you a few cuttings.

Good luck! I used to have this, but don't have it now. I had to move overseas and all of my plants were given away or sold.
