Okay, this is embarrassingly easy!
Wire (I used bailing wire, but any bendable yet somewhat strong wire will do)
Ornaments (I got mine at Target for $30 for a set of 100, I used about 200 on this)
Measure out your wire so it’s the length you want. Just bring it over to your mantel, door or window and unroll it in place. Cut it.
Prep your ornaments. I admit it, I bought cheap plastic ornaments (you don’t have to worry about breakage when you store them). The down side is the plastic caps kept popping off. To solve the problem, put a drop of glue where each cap touches the ornament – that will hold them on.
Make a small loop at the end of the wire so the ornaments won’t slide off. One by one, slide the ornaments onto the wire. Mix up shapes, sizes, finish. I did mine in all red, but mixing colors would be cool too.
Keep going until you’ve filled the wire. Put a loop at the end when you’re done. I finished mine off by hooking a big pointy ornament through the loop on each end.
Done. I wasn’t lying – that was easy.
