I've put together an activity for children three to three and a half years.
The idea is to teach them how to measure flour with a measuring cup.
I made the apron and the place mat all by myself.
You can find the Apron pattern HERE.
It's the same one I used back in July 2011 for these aprons.
The mat is just a rectangular piece of vinyl with bias tape around the edges attached with a fancy stitch.
