It tastes so sweet, feels so good, but don't forget it can burn you. Solar cooking is used around the world and is now making heat waves here in the Midwest. This workshop will provide you with the knowledge, craftsmanship, basic skills and techniques to build your own solar oven. Learn design & material considerations, walk through the building process and actually build your own oven. During breaks from building you will find yourself cooking some meals using different solar ovens (if sunny.) Even Minnesota winters can't stop the solar oven!

This five hour class gives you the opportunity to learn how to weave the northwoods greens into a circular holiday wreath. Participants will learn what greens to cut, how to hand wire them to the circle, how to decorate and make bows. You will start in the woods then end up at the farm figuring how to coordinate your 15 fingers and 4 thumbs.
