This was fun. I totally just guessed with this one. I drew an oval thing like this, that when sewn together makes a ball and hoped it would work.
I made the stem by rolling up a rectangle piece of brown and sewing shut and the leaf was free hand. I did stitch a line down the center of leaf to make it look more real.
At first it was very..um..bally so I sewed a couple of pieces of thread straight through the entire apple top to bottom and back to create a dent in center.
Here you can see dent in bottom…sort of
