The Hands and Hearts Middle Ages Discovery Kit contains everything needed for one child to complete all of the projects. Some materials will be completely used up and there will be leftovers of others. This kit is designed to provide only what is needed for one additional child to complete the projects. Each additional child will need an Additional Student Kit. This kit is only available for purchase by customers who are also purchasing a full Middle Ages Discovery Kit and is offered at this very low price as a blessing to families with more than one child. If you need kits for multiple students for co-ops or classes, please contact us for co-op prices.
