I've done both pipes, now I had to get down to the foot pattern. In the end it wasn't that difficult. Just to step on a piece of fabric, lay another piece on and pin everything together. I let there the gothic spike at the toe:)
To be sure I did some basting but it seems it'll go well. And these are final pieces. The left rim of the right one will be the point of attachment to the pipe piece, I won't cut it neat and fit it as the very last step.
