I have figured out a few things on this sweater as I have gone along. I learned that when doing a button band it is all important to cast on about 25% less than the number of rows already there.
I also learned how to make a yarn go back and for the in the middle of the row by locking the threads around each other when swapping colors ( color change). OK these things seam self explanatory but if you have never drafted your own pattern like this well not so much so it was a learning experience I am still working on it.
I realized I have a skein that is a different dye lot in number hoping it won't be a big deal. I am waiting to use it last and I am going to try and use it for the flap on the back if I don't have to see it it won't both me so much and I am definitely not looking at my back side all the time so that would be the best spot for me I would see my sleeves so that won't work for me there plus I think it will be less noticeable to other people as well on my back side. We will see if it is too much I may do some redrafting of the back side like make it all black seed stitch for the flap. The reds do look real close in skein form so I am hoping that it won't show either way.
