I would lay it out just to make sure you get it right, and you could always stitch them to fabric so that there is one uniform color all the way around. That way it doesnt matter what the width is, And then if you wanted to you could fill in any gaps with more ties. (I can see this in my head, just not sure if I am describing it correctly)

I'm not sure it would matter. If you make the skirt so it looks like a 'C', the ends are going to overlap in the back of the tree and any differences would be camoflaouged. Here's a link for a necktie skirt that might give you some hints.

Hmmm.. hadn't thought about having to sew it to a background fabric (which I had hoped to avoid).

Adella, thanks for the link! It's got me thinking now. I would rather hand-stitch so the zig zags don't show, but I had also planned to use the entire tie from tip to tip.

I need to figure out how many neckties it takes to make a circle.

I saw this done somewhere but you have to open the back seam of the tie and then sew them together.

Sharon,
Thanks, that's another good point to ponder!

Opening up the ties would supply more fabric, but on the other hand wouldn't give much "body" to the skirt.

Just went and looked at my son's tie collection, and they're sewn together pretty good. I'll have to decide if I have the patience to rip out seams without ripping the silk.

Here is the directions for a regular skirt but I'm sure you could improvise.
