Celtic Knot necklace

I'm not sure if the site requires a login; it's Lion Brand patterns.

I have difficulty wearing a lot of jewelry because my skin is sensitive to at least two metals, so even nickel-free jewelry often doesn't work for me.  I have a small cadre of pretty pieces that I've bought or that friends have given me, mostly in sterling silver, but I often forget to put them on because I never got into the habit of wearing jewelry very much.  I could wear a knit necklace.  I just need to get a spool with small pegs on it, so I could make it up in one of my fine-gauge yarns for a less-cumbersome look than the one in the picture.  Elizabeth's spool is designed for chunky-weight yarn and the stitches for worsted weight look too loose for my taste.  I might look up less bulky versions of a Celtic knot, too.

I have a purple Malabrigo that I couldn't decide on a project for.  I bought it because it was gorgeous, and I take it out every now and again to pet it.  I think I now have a possible project for it!
