It turned out PERFECTLY! A trick for bright red dough-- use half red food coloring, half magenta. It came out a lot brighter. I've also heard of using red kool aid powder for both a brightness boost and a better smell. I kind of like the smell of playdough though-- but I'm a weirdo, so if you want to use kool aid, by all means, go for it.
I made six colors using gel food coloring. The red is quite a bit brighter than it is in this picture.
I put them each in their own Gladware container to keep them airtight. Perfect sizes!
Then we got clay hammers in the mail, so we let Aubs play with the playdough. Ignore the stuff in the background-- we were switching all of her baby stuff out and toddler stuff in, so there was a bunch of stuff waiting to get store in the garage.
Another hit :)
