In keeping with current trends, I too have gone a bit loco for studding. But seeing that it usually hikes the price of an item of clothing right up, I thought I would do a bit of DIY.
You can buy studs off eBay for super cheap. Mine came from Hong Kong within 10 days. All you need is time, patience and a steady hand. Pay attention to spacing when doing it. I underestimated where I wanted mine and now have little red dots where I marked it which I'm gonna scrub off.
Carefully, snip a hole into the fabric. It doesn't matter hugely if you over shoot it a little because with a bit of navy thread, it can be stitched up again. The studs just screw together, as you can see, so it's super easy and cheap to add a little bit more edge to a denim jacket.
I still have a few studs left so I'm eyeing up a dip dye jumper I have.
And let me know if you give it a go, I'd love to see the results!
