I did! Mine is actually shoulder-length, but I have a leftover length of tulle that should be long enough for a chapel-length veil and I might make one of those, too, so I have a choice of which to use

A pattern isn't necessary, I actually free-handed my cuts.  Really all you need to do is round the bottom edge of the tulle.  You can also make your own pattern with a large piece of paper.  Use two pencils attached with a length of string to make a "compass" and draw the desired shape onto the paper, then pin the tulle to it and cut paper and tulle together.

I think getting the right shape was harder for me because I wanted my veil very, very sheer at the comb, so I had to shape both the bottom and top.  On my first attempts, I just left the top straight, gathered it, and attached it to the comb, but it was much too full for my liking.  It looked good otherwise, though!

For edging, I just ran some button thread that matches the color of my veil along the edges. You know how tulle has the little open squares?  I went 1-2 squares in from the edge, and just did a simple running stitch along the whole veil (except the edge that attaches to the comb.  It looks like a tiny pencil edging.  But if you do a good job cutting the tulle (use VERY SHARP scissors or a rotary cutter) it looks fine unfinished.

Good luck!
