I realize it is still hot as Hades in my corner of the planet, but I'm posting this anyway since some of my readers are in Australia and I think its already cold there. Yeah. That's what we're gonna go with.
Actually, the truth is that I only ever seem to get struck with inspiration for winter crafts in the heat of the summer and vice verse.
Seriously, tho, this is stupidly easy. String your beads or pearls. I just used a broken bracelet because it was the exact length I wanted. Make sure that if you are stringing them, to tie or crimp bead the ends around a jump ring so you can use it to attach them to the earrings.
Find a good place in the back of the earring you can wrap the jump ring around, then twist it closed.
That's it! These are super cute and give you an excuse to buy the earrings you see out and about, but can't wear. That, and they're great for actual function when you live somewhere super windy that threatens to remove a cardigan if you don't button it up.
