See those cabled gift card holders up there? I made 'em. I feel good about it. They looked even better with the cards in them, and they probably would have looked fantastic if I was better at button placement and had some appropriately colored thread for the buttons. But it was a nice little project and a more personal touch for a gift card. The pattern can be found here, and it features front and back cables.
I'm not sure why I thought back cables would be very different from front cables, but there you go. I read the pattern and panicked a little because I'd only practiced with front cables, but then I tried it and was almost disappointed because, oh, your held stitches are in the back. The right side has front cables and the left side has back cables. It's just another way to make a cable, and to make your stitches move in a different direction. If you've already figured out front cables, then you can probably manage back cables.
But since there's no need to struggle, here's a video to show you!
Video can also be watched here.
I tell you what, any task seems so much more manageable after you watch someone else do something a few times. The first time around, I always go between "I think I understand" and "I don't think I'll ever be able to do that." The second time, I'm able to pay closer attention. The third time, it mostly makes sense. Some time after the fourth viewing, I feel like the demonstration might be something I could actually try out myself. This applies to knitting, baby wearing, crocheting, Knooking, yoga, baby swaddling, sink repair, and anything else that isn't a hair tutorial (certain up-dos are never going to happen for me).
I don't know that back cables will require that much preparation and video-viewing from you. I'm assuming you'll have an easier time with it than I do, and I wouldn't call it difficult. It's a fun little technique that makes the prettiest design. I'm blatantly biased, but I think you should try it out after watching the video. Maybe watch it twice.
Postscript: I realize this post is full of really country-sounding expressions. I can't think of a better way to phrase things when I'm tired. Or, as it sounds when I'm saying, "tahred." It's just a day for Arkansas blogging. Sorry about that.
