That's cute. I went to Hancock fabrics, with my DGD (she's almost three) and she told the clerk that we were at Hancock's and she needed 3/4 yard please. It was just to cute, that the clerk actually gave her a piece (6") of fabric. She often sits on my lap to help me sew.
It is a wonder what they pick up when they spend so much of their time "helping" us sew.
