It looks like Emily is a natural! Now, honestly, who had the most fun--Emily or Grandma? Maybe there will be an inexpensive sewing machine in her future so that you can reclaim your FW.
I can hardly wait until my 3 year old GD, Hailey, is at that point. She loves to sit on my lap and watch me chain piece. She keeps urging me on, saying "Nother one Nana! Nother one!"
