I started my quilting on the big mariners compass quilt and have done all the large sections in the ditch. I plan to do the compasses in the ditch also, then do the trapunto with some stippling. When I turn the quilt, I have some fullness inside the large sections..not much and I think it will be taken up perfectly with the additional quilting..however...should I unpin these sections now or unpin as I go (if I need to)? Hope this makes sense.
