Great sites thanks. I did a search and didn't come up with anything like this. Thanks Again.

Hi, I hate being a poster pooper but these crayon apron things were very popular back in the 70s. However, the recipients found that once the crayons were no longer nice and new and were indeed "short", they were impossible for little or big finger to get them out.

In my opinion it would be better to make horizontal pockets using something see through so that the color could be seen and the crayon could easily be retrieved no matter how short it got to be.

Hope this is helpful.
