Please note that a row is not a tier.  A row is the amount of rows of crystals the ribbon consist of and the more rows you have, the thicker the crystal ribbon will be.  This is for one yard, which equals 3 feet. It is only sold by the yard. The cake pictured used a little over 4 yards. It was a cake for 270 people.If you are unsure of how much ribbon you will need, please e-mail me the size of your tiers and if your tiers are round or sqaue and I can tell you exactly how much you will need. This listing is for genuine czech quality rhinestone trim banding and it is sold by the yard. If you order multiple yards, you will receive your order in one continuous piece or possibly two pieces. I also carry this in many different widths. It can go up to as wide as 24 rows. Just give me an email if you are looking for anything I don't have listed and I will make a custom listing. Color: clear crystal w/silver setting Width:  5/8 of an inch, 3 lines wide Size: size of stone in its setting is between 4 and 5 millimeters Shape: stones are pointed back, settings are pointed back, not flat Quality The quality of this rhinestone is second only to real Swarovski/Austrian trim. Please feel free to e-mail me with any questions you may have. Thank you for visiting my store!
