Good luck with that. I have done many Dresdens and always PP them. FYI, I got a bunch of blades and unfinished blocks at a yard sale from a very experienced quilter who measured carefully and pieced, but got each blade slightly off, with predictable consequences. I ram rodded a Dresden opportunity quilt. All the more experienced quilters said it would be too difficult, but found it easy with PPing.
I wish you wonderful results.
