Worn jeans

Both of my pairs of jeans are showing a lot of wear but don't have any holes in them.
I will probably want to buy new ones in the fall.
Should I:
Cut them to about 5" inseam and have 2 more pairs of shorts for general summer use?
Cut them really short and open the side seams and just wear them at home when I can't be nude?
Toss them and have 2 fewer items of clothing?
