OH sweet meats and cheeses, I hadn't thought of that. We only have hardwoods, so I can only imagine the horror of finding a big, smeared in blob in carpeting. UGH!!
I guess I'm the oddball because I don't mind at all. As long as the playdough is still soft, I don't mind the color mixing because it's good for their hands to be working the dough. My DD never got into play-doh but my DS and his buddies can play for hours, and the first thing they do is mash it all together.
What really makes my skin crawl is when there are small dried up pieces mixed in the soft play-doh! Yuck, that's gross.
My house can be a mess and I don't care, but if my daughter mixes the play-doh, I want to crawl out of my own skin. I feel your pain. Luckily they drop so many bits and pieces over time it eventually fades away.
i can't stand when my kids sneak it out of the kitchen and then i find dried up pieces all over the house! the worse is, when you don't see a hard, dried up piece in the carpet and, you step on it! ouch!
