Most of the ones mentioned are ones I wouldn't consider (DWR, GFG, Pineapple, crazy, Bonnie Hunter, etc) - as they are too fiddly for my admittedly short attention span. : )
I also pass on quilts where the instructions include anything akin to "and now make 256 more of unit A". Gah!!!
But, #1 on the list of things I will never, ever, piece is a postage stamp quilt. Sewing rows of tiny squares, numbering in the thousands, sounds like a punishment. Plus, at the end they look so busy & random it makes the colors muddy.
Now of course there are exceptions - I might find one I like. But, I still wouldn't make one myself.
