We've previously raved about our obsession with paper pom poms and lanterns, which make wonderful, inexpensive decorations for weddings, showers, and parties. We just love these paper garlands, balls, and snowflakes, from UK-based Re-found Objects.
For those of you who are looking for paper decorations state-side, we found a great selection of Mexican paper picatas at Lee Carter Company (above).
123 Party has a great selection of tissue paper balls, bells, and fans (flat circular shape - shown above) in a wide array of colors and sizes. We found this pretty tissue paper snowflake decorations at Target. We found a nice dove garland (similar to the one from Re-found) at Oriental Trading Company.
