So here is a non-step-by-step intro to diying your own pendants. You can buy cabochons (the little glass thingies) and the pendant parts from etsy or similar sites. Then all you need is some paint or in this case nail polish and a hot glue gun. I suppose any heavy duty glue would do, so choose your own preference!
My Asking Alexandria t-shirt paired with jeggings from New Yorker, jeans from ONLY, a handmade lolita skirt and H&M faux leather shorts. Also my H&M knee high socks and my Irish lucky shamrock socks. Cardigans are from Ellos and KappAhl.
