Love your TR-12, Cindy -- mine is just awful! And I was thinking your TR-10 could be your "humility" block. And I've also realized after finishing my first DJ (yet unquilted), that I can't remember which blocks I'd meant to redo but didn't, and when you look at the overall quilt, it's hard to find the mistakes or sloppy ones.
I remove the freezer paper after I've sewn the seams. It helps me line up the seams if I've cut a little more or a little less than 1/4" around each piece. I often use a lot of starch on these blocks, and the freezer paper doesn't stick as well on the starched fabric, so sometimes the paper falls off and I have to press it back on. I'm not particularly consistent about cutting off the dog ears, but I think more often than not I don't cut them off.
