I did one of the Boston blocks with chevrons last month. The skill was to do half squares and keep the points, then to have all the points match. I just got a new machine so I was trying to find the 1/4. This machine won't let me do the index card trick and the needle doesn't sit in the middle. It's over to the left. I set the machine on 2.5 which gets the needle in the middle and does a sant 1/4, but I had a problem with total sizing of the block. Now I know it's 1.0. and live with the needle to the left.
