Thresa, I totally understand re: the SF 555. I am back to working on mine; I started the build in 1996. I'm sure yours will not take this long. Yes, it is a LOT of cutting, trimming, planning, fitting, switching back and forth between pieces...but I found it to be worth it in the end. That's not to say that I'd build it again, though! I was in Hobby Lobby last week and witnessed a dad buy a Painted Lady for his 8- or 9-year old daughter; he was fretting about putting it together but it's one of the RGT ones and I told him he could do it!!! SO MUCH EASIER!!!
You will learn a LOT from this build. Also, it's a very pleasantly proportioned house when it's done.
I have spent the last few days constructing newel posts and gluing all the spindles to my staircases. Today I'll be laying the wood floors so hopefully I can install the staircases next week. Feels good to be working on it again; maybe I can get the furniture out of storage and into the house! The twenty-year project continues.
