Barak,
Welcome to the forum. It sounds like you're advanced already! What circumstances caused you to grow up in such diverse places? If you can, send some pictures of some slings you've made to Chris and he'll put them on the gallery page too.
As for the cradles, Jim Burdine makes traditional Andean split cradles. I'm not sure how advanced he's gotten with patterns, but he makes them. I never liked making them myself, because it's difficult to stop the color from the underneath strands from coming through. The only way to prevent that is to use quite a few strands for your wefts (I think that's the right word). I mean that you have to gather quite a few strands together so that your cradle looks nice, and is thick and wide enough. Then after you make the cradle, what do you do with the extra strands? Well this is why traditional Andean slings have thick braids adjacent to the cradle. Typically 24 I think, but perhaps 32 sometimes.
Besides the typical braiding, as you know, there are other ways that Andean's and others made slings. Zebra wraps and so on. That's a whole different ball of yarn. I prefer the braids, but I never liked having to do such wide braids adjacent to the cradle. The reason is, because they can't be continued to the end of the cords and so you must drop off atleast 8 strands--all of the sudden--and still make the whole thing look good. As I've seen in pictures, even the Peruvians have some trouble with that. So I worked out my own design that requires less strands.
The black and white sling uses a 16 strand cradle and 16 strand braids for the cords. No strand dropping.
I get questions about this, so it's good for me to lay everything out here to save myself the trouble of writing it again.
I made the cradle with a knotting technique I learned in a friendship bracelet book I got from the craft store, years ago. I heared there are websites about it, but I've never seen any. Boyscout or girlscout or something like that. Look up "friendship bracelet knotting." I'll send anyone who's interested, pictures from the book, on the basic techniques- just email me Whipartist@aol.com. They aren't great pictures but you can learn from them. You can see a few more pictures of my sling at
www.whipartist.com. I'll post some of them here.
I use a knotting technique called V knotting. Each half of the cradle is composed of two sections that knot together in the middle at a V like angle. You can just knot from left to right at an angle or from right to left at an angle, but if you adjoin the two angles you are able to make a more detailed product. Actually there are many complex patterns you can knot, but I stick with some of the more basic stuff because I think it looks better and produces a more solid cradle.
The complex part isn't the knotting, it's the actual cradle design. That took a few years before I really figured out how to do it right. My earlier slings tended to fray and wear at the edges because they were exposed to the greatest wear. Now I construct the cradles in a different way in order to make them durable. The inside of each side of the cradle has an extra section of material I use as a "wear pad" to take the wear of rock slinging from the main pouch. It also acts as a natural hinge and allows the cradle to naturally work in either an open or closed position. It's pretty cool.
Basically I split the pouch into two 8 strand sections from the split cradle, that adjoin into one 10 strand section that goes over one 6 strand "wear pad" and then encompasses it as I knot it together before forming the cords. It's side by side 8&8, then over under 10&6, then the strands from the 10 knot around the 6, then I do some knotted wrapping, then I do the cords. I convert from the split cradle into the 10over6s by taking each side of the cradle, dropping 3 strands from the inside of each side, and then continue knotting the two sections together into the 10 strand adjoining section (leaving the 6 strands hanging underneath). After I do that, I turn the thing over and knot the other 6 strands that were hanging underneath.
Now it would be impossible to bring two V V sections together, so I fill in the section inbetween with knotting to change the angle from VV to a big V again. I can't explain that, but if you figure out the other knotting, I think this section may become more clear to you with a little practice. I think you'll be able to figure it out between the text and the pictures.
Lastly, I forgot to add earlier, that I start each section of the cradle from the middle. This way everything looks symetrical. I have to do some more of that "fill knotting" to make it work, but it does. Some patterns work better than others for that. I hope this helps. It will make more sense after you've tried to do the knotting yourself. Write me and I'll send you those pictures of the book's pages.
Lastly, lastly. I put a few drops of elmers glue on the places on the inside of the cradle that take the most wear. It works very well to reduce wear down, though the design is durable anyway. You can see in the first picture where the glue is.
Hope that helps
Ben
