I think this is wonderful. Girls need a break, and this class is fun and enriching. Everything does not have to be brainiac or Limud Torah. Girls will be the mashgichim in their own kitchen and cooking and baking is all part of it.
I am sure this is NOT the only class they conduct but it is a good start. A school like this probably also teaches the girls something about nutrition (YAY!!!! Very important that most schools don’t touch), as well as sewing. Which in today’s economy would be a lifesaver for many families. Especially with the styles being sold and the alterations needed. Girls/women are creative. Knowing how to sew can be a great means to dress your kids inexpensively yet make them as cute and adorable as buying from the best store. I did take sewing in High School but my mom a”h was afraid I would break her machine so I didn’t really get in to it. I wish I did. I really wish I could sew today. My mom made linen for us either from fabric or from Flat sheets. Halevai I could do that today for myself and my kids. She made us beautiful clothes, if only I could sew for my grandkids.
As far as napkin folding is concerned Kudos on that as well. That is a lot of fun and we are all curious how its done, so good for them. Let the girls have fun while they also learn skills for later, along with limudei kodesh. They will work plenty hard once they get married.
