For a housewarming gift, my lovely friend Blair made us a beautiful little felted piece that says "if it's yellow, let it mellow. If it's brown, flush it down." This used to be our rule in the bathroom until Kyle told me about his german friend who kept his bath water and used it to flush the toilet with. I liked the idea so much that we implemented it immediatly (and i think Kyle instantly regretted having shared the antecdote!) The only problem is that I am a bit of a clean freak and if you leave the water in the tub, the tub gets very dirty. We now have a large tupperware container (i mean large, I could fit into it all scrunched up) and a big bucket and a small bucket. The system is this:
1.Put the plug in when you are having a shower
2. When you finish use the big bucket to scoop the water in the tupperware
3. After using the toilet, use the big bucket to "water bomb" the bowl of the toilet and everything will flush down
4. Put a small bucket full of water in the toilet so that there is water sitting for the next time
5. Use a towel to wipe up the water you have inevitable spilt on the floor

*****Alternately
3. Use the small bucket to scoop for the tupper ware and fill the big bucket to Water bomb the toilet. This way you won't splash water on the floor. Follow step four but skip five.
*** If the tupperware is already full, and it is nearing time to clean the tub anyway, you can leave the water in the tub, however; if the tub is sparkly clean and the tupperware is full, just fill the buckets and then pull the plug
*****If you shave a large beard, or your head, or excessive body hair while in the shower, just pull the plug and then wipe the tub down with a rag and some vinegar.

It's too much to embroider or felt onto a plaque and almost too much to remember! We did leave our housewarming gift on display because it was so beautiful, but many people follow the instructions and it means i have to clean the toilet every day because it stains! So, we hid the beautiful sign and for the most most, let guests just flush with the handle unless they ask us. I may just make another plaque the says " "Whether brown or yellow, don't let it mellow. Use the bucket to Flush-it!"
