Hairpin Lace 2

I've sorta finished the small neck scarf I made with the hairpin lace tool. I used bulky chenille. I made 2 panels of 140 loops per panel(70 loops on each rod) and only encountered one issue, I need longer rods when working with bulky yarns. This really does work up quickly and I can do it while sitting in front of the TV. I thought about taking one of my cross stitching loom things but realized that would make the loops to wide, even if I used the biggest crochet hook I had for the center, it still wouldn't be long enough. So now I'm looking to make my own hairpin tool. I want it to be adjustable but long and i'm thinking perhaps dowel rods would work or some thin metal rods like the ones I got with the tool I have but longer. We'll see how that goes.

Here is a few pics of my 1st hairpin lace piece. I need to make a scarf pin for it or find one. It's small, a neckkerchief.
