To my Social Links header, the love button up top. I added my Pinterest and Instagram there, for easy access.
I have nothing on Instagram, I don’t know if I’ll ever add anything on to it, but I might and it might fill up one day.
As for Pinterest, I pin lots of DIY and hair stuff, as well as those relating to personality types and personal development. Completely different from anything on my blog, just warning you, but they do interest me. And if they’re the sort of things that interest you, you might like looking them up too.
