The effect of slightly different procedure.

Here is an example I tried to finish step 2a (extension of inner-rim outward) as mentioned in the previous post first without connecting the inner-rim into a cylinder. Since there are two many beads in the outer-rim, the resulting structure shows interesting ripples. I found that it is quite difficult to weave using this approach. I made many mistakes, so I have to do many tries before I can get the right structure.
