My orange
Welcome! For my orange, I first started with making a sphere and smoothened it (the stem wasn't added yet I just forgot to take a screenshot beforehand).
I later coloured the orange orange obviously, in material properties. I tried painting it but since it didn't work, I had to use the default colouring method.
Last of all, I added a stem by first denting my rounded orange at the top, then (somehow) stretching the dent to create a slim stem. I then coloured it green. The stem looks more like a single leaf so I left it at that.
As you can probably tell, I forgot to take screenshots for quite a few steps but I hope you don't mind too much...
