If you're mom didn't pack some of this in your send-you-off-to-college bag (mine did!) and you're not familiar with this stuff, let me just tell you: it's magic. It's an iron-on adhesive used to bond fabric and works like a charm to quickly hem pants or make fabric banners, in my case. Also, it costs $1.77 for 8yds and you can buy it at Walmart or any other crafty store. Love, love, love it.
So you need 3/4 inch Super Strength Stitch Witchery (or something similar), an iron, fabric, and 7/8 inch ribbon.
Now, go cut out a bunch of isosceles triangles. Don't measure. Just eyeball it. That's my method and it works just fine. If they're a little uneven, just go with it. It's called: visual interest.Now, roll out your ribbon and then roll out some Stitch Witchery right on top of it. If you use the measurements mentioned above, you'll see that the fit is perfect.Next, I overlapped triangles upside down side-by-side on top of the ribbon-Stitch-Witchery combo. You don't want to be able to see the Stitch Witchery because if you iron directly on top of it, your iron will get sticky and that's no good. Hold your iron on top of the fabric-Stitch-Witchery-ribbon combo for 3-5 seconds and it will adhere. Repeat until you have the length of banner that you want. And, voila. You've made yourself a pretty little no-sew fabric banner. And, believe me, it will make you really happy. I strung mine up in the living room for blog's sake only. I have other plans for where it will really go. Also, it cost me under $5 to make. Though the fabric was free this time, you could probably get enough triangles out of a yard to make a fairly lengthy banner (I used around half a yard total and my banner was 18 feet long). It didn't stay up for long because Becks thought it was a little out of place in the living room...Come back next week to see where it will hang :)
