Consider getting a laundry basket or dedicating a bin of some sort to laundry in each bedroom. Also, have a few extra in your bedroom. (I don't want to get in a habit of suggesting you need to buy "organizing supplies", since that's not usually necessary. Repurpose a storage tote, canvas bag, etc. to save money.)
Here's what I do with my five baskets:
- Towels and rags
- Delicates/dress clothes
- One basket in my son's room for his laundry, which I don't separate by color. His dirty towels and washcloths go in here.
What's really great is that I can do laundry throughout the week when I see that it's accumulating. No more mountain of clothing to sift through on Saturday morning. That's precious family time nowadays!
