<p>Things to consider before ordering:</p> <p>Ccount how many windows you plan to use the rings on, then multiply that by 14 to figure out how many rings you will need. (6 windows = 84 rings).</p> <p>Generally a window's curtains will require 7 rings per side if you match where their built in loops are, so that's 14 rings per window. you can fudge this a little to make the quantity of rings work, but too few rings and your curtains will be really saggy.</p> <p></p> <p>Things to consider before ordering a specific size:</p> <p>Measure the girth of your rod to make sure the rings will fit over it.</p> <p>measure the distance from the wall to the rod. the distance from wall to rod needs to be at least half of the full width of the rings, otherwise you risk the rings rubbing up against the wall.</p> <p></p> <p></p> <p>Tips:</p> <p>Some clips were a little hard to open, I recommend you take a pair of pliers and gently squeeze the clips open( no resistance if you squeeze at the very top of the clip), once opened they were easy to open and close.</p>
