I reuse plastic containers that meat, deli, etc. come in. I haven't bought storage containers in years. I, also, use pieces of cardboard covered in foil to put cakes in a cake carrier, or cookies, muffins, etc. to sit on in a plastic bag. Newspaper for fires, projects, or wrapping paper. Wash reuse plastic plates, cups and dinnerware until they start cracking. Melt used scent tarts and add oil fragrance. Use plastic produce bags from the grocery to collect meal scraps, or coat meat with bread crumbs, etc. Use saved paper bags to send leftovers home with my FIL every Sunday. Use my last year's at a glance calendar pages to make notes, lists, etc. Used fax and copy paper torn in half to make notepads for hub to makes notes and doodle on in his office. That's all I can think of for now.
