You can use medical or food tubing to weave cool stuff, the same way you do with paracord craft.
Step 1: Material
you need about 8 feet of tube and a buckle
Step 2: Mounting the Buckle.
you insert the tube in the male half of the buckle, the same way shown on the picture.
Step 3: Getting Ready
you insert the tube in the female part the buckle, and you'll end up with four strands. The two middle ones will be the lenghth of your bracelet, and the two side ones, are used to weave the cobra pattern braid.
The cobra pattern pretty much uses alternatively two opposite side ties. first, bring the right strand towards the left side, going over the two middle strands and under the left side strand. The latter will then go right, under the two middle strands and under-through the right side strand.
The second tie is the same as the first, but starting with the left strand.
keep going right- left, left-right....
Step 7: Ending...
untill you get the end, trim the excess of the tube.
Step 8: Final Product.
Step 9: Extra Extra!
You can make cool stuff with medical or food tubing. They come in different sizes and flexibility. So far, a 1/8 outside diameter looks ok, but with the inside diameter being small, and the wall of the tube thin, it makes it a little hard to flex. I'm still trying to get more samples to see what works best. For the colors, you can inject paint inside the tube, let it drain and dry and you should have colorful tubing. thanks for looking! :-)
