Nice photos. Hope your canvas dries okay. I generally enjoy schools days at reenactment events, except for 2016 when we had a group from a particularly snotty girls school, who were thoroughly rude and disruptive. But generally kids are great, and often ask questions that lead to really interesting discussions. And they want to know about the stuff that interests me, such things as what people ate, wore or used for medicine, what stories and songs they knew, what people did to pass time before there was TV, what games people played, what school was like and such. And demonstrations such as cooking, making cider, mead or beer (the muscular lads are always willing to lend a hand with the cider press), and making cold cream and getting a sample to take home for their mum are always fun. I use a Roman cold cream recipe that persisted through the middle ages and is still used in the present day.
I am usually in the same pavilion as the Viking field kitchen, so I bring in big containers of growing herbs and vegetables which both of us can use in our demonstrations, especially if it is one of the years I am running the apothecary workshop. Just near us we have the tanner (the kids love his work because it is smelly, gross and very hands-on), the cooper, the in-progress Viking longboat being worked on, a bloke building handlooms, making spindles and such small tools, and a musical instrument maker, who this year made a kantele.
In 2020 I think they want me singing and storytelling, and perhaps doing the apothecary.
