Lavender Runner with Lace weave

I didn't measure the length on loom very accurately - I don't think I really had that much take-up.  This was my first attempt at working with any lace weaves.  The yarn is a mystery fiber - I bought a couple used cones off ebay.  My best guess is a polyester   It's a little bit stretchy and I do believe I would have been happier with the runner if I had used a sturdier yarn.
