ice cube trays for jewelry or nuts and bolts in the garage....
Great Laundry idea. Could also do different categories: kids clothes, work clothes, undergarments, sports wear, towels, etc. Also, considering hang a piece of fabric over the laundry bin holders so it looks nicer. Choose a nice fabric, use small nails or velcro to get it to stay up. Another user said use 4 tier plastic shelving, a shelf for each laundry basket.
Use cake stands or tiered plant stands to declutter your bathroom counters!
