I felted my booga bag yesterday, first time I have ever felted a knitting project. I watched it very carefully on advice from a couple of knitters on the knitter's forum (knithelp.com) and it took only about 10 minutes or so. I kept checking it so I am not all the sure exact time, but it didn't take long. My only problem was that when I shaped it on the box I noticed one area that felted on it's self together, as well as some parts of the I cord edging felted a bit funky. Next time I will be more careful to make sure it not bunched up in the pillow case. I must say that the smell of that wool was awful! Glad it doesn't smell that way when it's dry!
After it dries completely I will post the measurements. Here is a picture I took yesterday after I shaped it on the box. My kids think it looks like the Cat's Hat from "Cat in the Hat!" I am going to see if I have some fabric and try to line it.
