Here is a recent creation. The valances are a simple design, obviously, but I was working without a pattern and these are lined, so I had to figure out some logistics on the pocket for the rod. Also, finding a large-scale curve for the bottom was tricky. I ended up using a large oval tray and my cutting mat to map the total length of the fabric portion that needed the curve, alternating the platter up and down.
I found this fabric at FabricLand in New Providence, NJ, for $35/yard - a little dear for me. But, I was struggling to find just the right fabric - a black-and-white base, with a retro feel, and with some color in it that would integrate into the dark orange and navy blue in the adjacent room. I fell in love with this fabric, and it was as cheap as anything I was seeing at Mood, so I went for it.
Later, when sewing, I noticed the maker and name of the print along the selvage of the fabric - Pom Pom Play, by Waverly. I started thinking about making some matching napkins, and googled the fabric name, I found the same fabric available at HouseFabric.com for much less than I paid, only around $17/yard. I plan to buy from this site in the future. The only bad thing for the site is, I think you need to know what you want to buy from it, because they give you only a small image of part of the pattern, and I would not be comfortable dropping say $50 for total fabric needs without seeing a bigger image.
The trim I found at M&J Trimming in the Garment District (6th Ave between 37th & 38th, they also have a great website if you are not local, or are just lazy, www.mjtrim.com). It was not exactly what I was hoping to find, but I wanted orange, and I wanted retro. I like how this trim works on the finished product. Also, though, I sewed it directly on bottom edge, so if I find something else I like better, it would be pretty fast and easy to pull this off and put something else on.
I am happy with how they turned out! They are so cheery, and look nice on these enormous old windows.
