Thanks everyone, for the kind words. I was so proud of myself, I just kept going in to remind myself of all the work I had done!
To answer a few of your questions - it took me about 4 days to finish the job (my DH says once I get a "bee in my bonnet" everything else goes by the wayside until the job is done.
The shelves are from Lowe's. They probably have them at Home Depot. Amazingly, they fit EXACTLY into the space. They are in there so tight, even a California earthquake won't affect them.
For the fat quarters, I rolled them around a 4 inch ruler, just like I did with a larger ruler for the larger pieces of fabric.
Thanks again, everyone, for the kind words.
