It's massive and there is so much to take in. I don't think it's possible to notice everything without spending hours in there. Because it was one of the busiest tourist weekends of the year for DC it was pretty crowded, but we were still able to get up close and see most of it. I was loving it! While I'm more of a knitter, I did start with crochet and I still revisit it once in awhile. If you are in DC, even if you don't work with yarn, this is too cool to pass up!
