To sweat or not to sweat

Both sweaters have been growing. Unlike our grass...

The short sleeve (to not sweat) only needs one more increase then some inches, sleeves, and ribbing around the head opening. It seems huge when I hold it up but when I hold it up to my body it seems like it will fit. Odd.

The back of the hoodie (to sweat) just needs a few more inches. I'm not sure if I'll cast on for the front when I'm done or if I'll wait until the fall. I really have no desire to knit wool in the summer. And I'm sure I'd find a need for my size 7 needles. But then I'm afraid of never casting on and then never finishing. But then maybe that fear will make sure I do cast on in the fall and do finish.
