I have been know to say, "I have enough scrap clay to pave my drive way." It is true. I have a tendency to lose track of how much good clay I have. I am a very visual person and have repurposed a wood Pepsi box to keep unopened clay. I love my Pepsi box. It stands upright and each section holds five 2 ounce blocks of clay; it looks cool displayed like that. But once a block has been opened I tend to use part and then put it "somewhere"; Lord knows I would never want to put a opened pack in with the ones in my pretty, pretty Pepsi box. Like it has to be...perfect.
Recently, while cleaning my clay area found lots and lots of partial packages of the same color and realized just how much clay I have---all over the place. Many of these treasured finds had other colors of clay mixed in or were dusty from sitting opened. Wow, I really do not need to worry about running out of clay any time soon. I found a very inexpensive way to keep opened clay clean and tidy. Ziplock sells plastic containers and the square one to be the perfect solution. My local grocery had them on sale for $1.99 for a 5 pack. I really like them because they are large enough for what I need and I can see the color through the plastic; the raw clay does not stick to the containers. They can also be stacked-that makes me look organized even though I am not. This is an easy way to see my inventory before ripping open a new clay pack. It is also great to keep a smidgen of custom mixed clay with the same color family.
Now my scrap clay pile is really scrap clay rather than for something when I cannot find a home.
Hope you find this tip helpful. Clay On !!
