A DWR is extremely ambitious, I just did my first one not too long ago for my sister and it does require time and patience. Should you choose to go the DWR route, might I suggest you check out Shar Jorgenson's tutorials on YouTube, they were extremely invaluable to me. She broke everything down, explained why the connecting corners are better on the bias, how to check for a scant quarter inch seam allowance. I had those tutorials on repeat the entire time I was working on my sister's quilt. Once you get the hang of it, it's actually not that hard and I was able to conquer my fear of curves. If time is a constraint, then maybe a log cabin or an Irish Chain in their wedding colors would be better and faster.
