If two colors are good, are three colors better? This is an 8-shaft M's & O's with three blocks, each with a different color. I used the same three colors for the warp and weft. You can use different colors but you definitely want to sample first if you do because you can get some weird effects.
The way this was treadled, I put the floats in the blocks of solid color. Notice that the floats are in the blocks with pink warp and pink weft, etc. With a different treadling, you could move the floats to blocks where you have mixed colors if you like.
With this structure, it's hard to get really nice selvages if you use three weft colors. In this towel, I carried both unused weft colors up the selvages. When doing this, I think there will always be times when the two unused wefts will be on opposite sides of the fabric and times when they will be on the same side. Maybe there's a way to avoid this but I haven't tried to work it out. In any case, if that happens the places where both unused wefts are on the same side will be slightly pushed out from the blocks where they are on opposite sides, so you get wavy selvages. Mine weren't too bad, but this is not the structure to use if you like great selvages.
I haven't done anything more on my Dorothy, although I do plan to do something tomorrow. I just don't know where the time goes. I'm retired, so I'm supposed to be sitting around with my feet up staring into space. Boy is that wrong! I think I have less time now than when I was working - but I have no intentions of going back ;-) The problem is that when you're retired, everything you do is something you like (except the chore list that your working spouse leaves for you) and it's really easy to get overloaded. I try to make weaving and writing priorities but this week I've been painting trim on the house among other things and weaving has slipped a little.
This is the last of the M's & O's -- the next post will be honeycomb.
