She made it herself at all of 7 years. I got half a metre of 112cm wide material (she chose a purple cotton) and some elastic for all of $4 (Australian). We sewed one seam, making a tube, made a waist band and put the elastic in and did the hem at the bottom. This is the first time she has used the sewing machine but she only needed help with guiding the fabric. We had to put the foot pedal on a stool so she could reach it! The bit she loved best was when the bobbin ran out and we had to refill that.
It's not exactly haute couture, but it's her first attempt and she's as proud as punch. I'm so pleased that her first project was so much fun. Thanks to all for encouraging me to give it a go. We both can't wait to choose the next project.
