Ever since my girls were old enough to ask to go to Maker Faire (about 3 years old), I set a rule: if you're going to travel with me to a faire, you need to do two things:
(1) Make (or help make) your clothes for the faire
(2) Present, volunteer, help at an exhibit, or participate in some other way
We've followed these criteria. Sage's first big Maker Faire was World Maker Faire in 2012, when she was four. She helped sew a dress, and built a Nerdy Derby car that she brought to NY from MN. (This car makes a cameo appearance in The Art of Tinkering, if you look very closely.)
In 2013, Sage was five, so we discussed the possibility of presenting at the faire. She was up for it, and volunteered to teach a workshop on Squishy Circuits. This year she also took the lead on making a jumper with pockets (for LEDs) and big wooden buttons.
About two weeks ago when Sage and I were invited to the 1st White House Maker Faire and run a Squishy Circuits table, and we jumped at the chance. Clearly, it was time to make a new dress! Sage had just finished kindergarten and had a free day to work on it, so we decided to be adventurous and make our own pattern, based on an older dress that she likes. She made some modification, traced, cut, pinned and sewed. (Since we used the serger, I "steered" and she worked the pedal.)
Unfortunately, we completely forgot about seam allowances and the first dress was too tight. Sage picked new fabric (very patriotic in stripes, white, blue and pink) and made a second version.
