This DIYs are not by me. i found them while randomly surfing and thought I'd share.
The first DIY I found on the "Hey You - Get Off My Cloud" blog. It is for a tee adorned with crystals. Check it here http://www.bloglovin.com/m/46540616/0 or here http://heyyou-getoffofmycloud.blogspot.com/2009/09/diy-1.html
The second DIY is from "Style Scrapbook" blog. It is for for the famous Balmain jacket with the rope-like adornments on the front and on the shoulders. See it here http://www.stylescrapbook.com/2009/01/diy-balmain.html
Both are very much worth checking into!
