ADD here. I seldom use a pattern, but when I do I’m likely to do some, go play with another quilt, do some more, go play with yet another quilt, do some more, etc. Working on Bonnie Hunter’s On Ringo Lake a few years ago taught me that I do not like making all of one unit before doing something else- I found it to be excruciatingly boring trying to make 100 subunits at a time.
