Perusing Etsy (like I do), I came across these Custom Yarn Hair Falls ($40), or extensions made of yarn instead of human hair or synthetic fiber. At first I didn't know what to think, but then I thought, "Why did this not occur to me as a child?" After all, yarn is bright, colorful, inexpensive, and easy to put in your hair, and teenage Bella would definitely have appreciated some fuzzy, bright pink hair. I don't know if grown-up me feels the same way, exactly, but given the nastiness of the human hair trade, I'd say yarn is a whole lot nicer and less controversial. What do you think, though? Are these ladies on to something?
