If you like to knit, scrapbook, sew, or pursue some other craft you probably have plenty of "leftovers" including yarn, paints, buttons, and fabric. Why not donate items you no longer use starting August 11th thru the 16th, and then come back on Saturday, August 18th for "new to you" materials!
Find "new to you" craft supplies and seasonal decorations at this library craft swap. Those who donate will get first pick and then it is open to the public. Any leftover materials will be donated.
Ask at the Reference Desk for a list of acceptable donation items.
