Let's celebrate the Earth Day by saving things from going to the dump!         If your sewing machine never gets tucked away, your toolbox, glue and scissors are always ready for the next project, or you're just looking for some creative inspiration, we have you all covered.         We have collected expired and unwanted material samples for reuse and creative upcycling by educators, artists,DIY-ers, and crafters. Some of the things you might find include fabric, carpet, wall covering, wood, tile, stone, glass,rubber, and much more. Crafting with children is always fun, so there will be free activities for the kids too, such as bead crafts, clay modeling, collage, etc. Come join us!         The event goes from 9 am to 2 pm at FloForm, 5320 E. Sprague Ave., Spokane, WA.         NOTE: If you want first dibs, you've got to register by 5 pm this Wednesday to get in the door 30 minutes early. It's free, so what are you waiting for? Don't forget, the event is also BYOB — bring your own bag or box to carry your finds home.
