Here are instructions for an intricate Kelt cable inspired by an old manuscript. Add this to my swatch list for cables.....
Loving the cables. Grumperina gives a nice tutorial on cabling without a cable needle.
Here is a really cute sock pattern with tulip cables....if you can read German. There's a chart though which should simplify things. ***ETA--the pattern and chart for this is now a free Ravelry download in English*** She has some beautiful patterns....interesting cable-y entrelac socks
Here's another cable pattern from girlfromauntie: the double knot cable. Looks really nice.
These X's are interesting too. There are a huge assortment of charts for different cables on her site. Wow, you don't even need your own stitch dictionary!!!!
I would love to swatch the cables as a project. Just to do all of them, wow that would be so cool! Unfortunately I have a job, and other knitting goals to interfere with this idea. Oh well, maybe when I'm semi-retired....(yeh.)
