I do like citruscountyquilter, except that I also measure when the quilting is finished (so I know how much binding to make) and after the quilt is bound and washed. The reason for the final measurement is so I can fill out the quilt size for my journal of completed quilts, so I know the size if entering a show, so I can mention the size if I post about the quilt here, and so I know how big it is if I'm looking for a quilt to gift someone. I can't say that I have actually compared the size before and after washing, but I haven't noticed a lot of shrinkage, probably because I prewash my fabrics, I quilt fairly densely, and I often use poly batting (though not always).
