I have put a ghost warp on the Megado. Various points to note. You have to decide what epi is going to be used for the main weavings and then the ghost warp needs to be the same or very near the same epi. Since the ghost warp is not being woven for use, you can use what yarn colour you want in any order. Also you can mix the yarn sizes provided you are not too far from the main one. So there were 720 ghost warp ends and I did tie on and weave a bit looking for errors. I found two in 720. Not bad going. Now it is all done and I have two sets of lease sticks in front of the reed, one is the ghost warp and one in the first true warp.
Will post some photos when I start tying.
