Welcome from on the road, getting ready to leave the snowy city of Detroit (UGH). Know why everyone else is going somewhere else, for sure. I am also working on a hexagon paper piecing right now with 3" hexagons. Your's look a bit smaller than that. Yes, it's quite an endeavor, but you should see the first quilt I did. We learn from experience, and seems to me you are doing a great job. If you love your choices and love what you are doing, that's 90% of the project. Post the pic when you finish it.
