I have long loved all things garland. Nothing says special occasion better than some pretty fabric or paper hanging from above, swaying gently. As an added bonus, garlands, banners, bunting, whatever you call it, packs a lot of decorative punch for relatively little DIY time and effort. There are lots of great tutorials out there. Here are a few simple ones to get started.
While this tutorial from craftstylish is technically for a mobile, it could easily be adapted to make a garland instead. Try one out for your next party, or make a pretty one for a new baby's nursery. Or just for yourself!
