Good things take time. It took about nine months from the idea to the completion of the sweater.
The effort was worth it, as the optical illusion of the elephant looks stunning even as a crocheted piece of art.
My celtic tree gets a lot of attention. To be precise, I was asked if I would be willing to crochet it again, perhaps as a jacket? Well... yes! When I was finished with my first version, I thought "if I ever do it again, I want to try it with multiple colors". Guess what? I also did that. And some additional improvements which I came across when crocheting/finishing the first version. For example, I did not like the horizontal leaves as much as the others.
Also, as promised, I digitalized my pattern and now you can give it a try yourself: Crochet Pattern for the Celtic Tree Jacket
