Here's a really easy DIY project that I made to add some color to my living room (like I needed that...) All you need is yarn, hot glue and a pack of colorful feathers from the craft store.
Start out by measuring the length of garland you need. Mine is about 4 feet so that I could hang a double strand over my mirror. Then choose the feathers you want to use - I chose to rotate two complementary colors, but you can use all the same color or just mix a bunch of colors together.
Take your hot glue gun and attach the yarn to the spine of each feather, leaving about six inches between each. Let the glue dry, then hang it up around your home. (told you it was easy)
I even ended up making a few different strands because I just can't stop making junk to clutter up my living room walls. Minimalism just isn't my thing, I guess.
