Sandy, I can't figure out how to respond to you personally about Brandywine, so here is my answer. Yes, there are YO's on the center stitch in Chart A. That threw me a bit at first also, but plough onwards. Those are meant to be there. The only glitch I found was on Row 37 where it seems to me that a YO/SSK is missing from the top of a diamond pattern.
While teaching them to knit I came up with a memorable way to illustrate gauge. That seems more like podcast fodder than blog fodder, but here's a shot at it. The basic idea was to have all three of us stand at the same point and take 10 steps forward. We all ended up in different places. I explained that is what it would be like if our steps were stitches. One knitter's 10 stitches would be bigger than another's. Then I explained that the needle size is just an average, a guideline, and they should experiment with different size needles to get the recommended gauge rather than change their knitting to be looser or tighter. I hope I got the point across. At any rate, we all needed a stretch and a wiggle at that point so it was a fun exercise.
I like it that they call me "Tante Paula". "Tante" is Danish/Norwegian for "Aunt".
Yesterday we made lots of bubbles in the back yard. That was so much fun! It has been a long time since I've blown bubbles. We had the big wands and lots of strange-shaped wands also. I think bubble blowing should be a regular activity.
