At what age do you think would be to start having your daughter do her on laundry?

My daughter is almost 13...she wears about 5 different outfits a day, then puts them in the laundry basket. I want her to see how much more work she is causing me. So I think she's old enough. Am I being to hard? Dad says I am.
Update: this is great, getting answers from teenagers too! I guess I just thought since I am a stay home Mommy...I need to do it all. But geshhhh enough is enough!!
