Elizabeth Hartman's patterns are a bit, shall we say challenging? I did the Dogs in Sweaters. I cut so carefully and put everything in labelled baggies and still had a few of the wrong sized pieces. I had to recut a bit and had some leftovers. I had to do one block at a time and work very carefully. It wasn't something I could take to a quilting bee (I learned that the hard way). I got it done and it's adorable, but her patterns are definitely not for the faint of heart. Especially if you aren't used to working with all those tiny pieces.
