Have your kids outgrown their clothes and are in need of the next size up? Bring their old, but still wearable clothes to the PDX Kids Swap at the Multnomah County Library’s Central branch on Saturday from 1-3 p.m. You can swap their too small-clothes for just-right clothes. You can also swap accessories and toys. How economical and green is that? Be super thrifty/green and take MAX to the Central branch instead of driving. The Central branch is located at 801 SW 10th Ave.
