I do all the cutting, lay out each block the way I like best, stack the blocks, at machine take top block and sew the first seam, continue to the bottom of the stack. Clip the threads between each block (4 squares), then make a new stack and sew the second seam, all 4 squares are sewn together. Clip threads and then press.
E. Burns does her flip/sew and it is easy to keep them all in the right place.

Same here, I can screw up enough without asking for it, lol.

Inexpensive paper plates also work well for separating each block.

I've rearranged my room so that my design wall is directly behind me as I sew. Makes it really convenient to just peel a block off the wall and sew it together. I can cut it all, bring it to the wall and arrange it there to make sure it's all in the right order, then just sit and sew it all together, putting finished blocks back up on the wall.

Works as long as I'm just doing a small section. Still have to get up a lot if I have a whole queen-size laid out on there, lol.

Thanks for more suggestions. Farmquilter, I like your idea but probably will have to get thru this first attempt at D4P before I'm comfortable enough to try. Wildyard, I really like the idea of using paper plates to separate the blocks...easier to work with. Now, just to get ready to make those cuts. Will have to wait until next week as I have to work now thru the weekend.

sewnoma, what a great idea, wish I could do that in my room but placement of the window and my small space makes it not realistic. My sewing space is in the center of the room with storage on all the walls.
