Castellated finish

At the end of my weaving I thought I would try out a new finish. It's a pig to do but I thought it would be good for a wall hanging which is what I think this piece will be. This bit of weaving is about five feet long I think and it is a sampler of patterns on a rosepath threading as set out in "A Handweaver's Pattern Book" by Marguerite Porter Davison. Hopefully I shall finish it tonight if I can keep off the computer.
