Tomorrow I am going to a "Christmas in June" lunch, and part of the fun involves a swap of hand-made Christmas ornaments.
Here's my completed offering:
I found this picture on Pinterest:
Annoo's Crochet World. However, my tree is not the same shape as the ones in the picture. It is much squatter. I can see that both the red and white trees in that picture have more rows than specified in the pattern, but I think they must also have less stitches added in each row of increasing, to give a narrower taper.
I don't have time to make another one right now, but if I ever try it again I would experiment with the increasing a bit, and also make the base a bit smaller than I did on this one.
