Those are all gorgeous! I have yet to take the plunge and do a Marfy pattern, but I love to look at their illustrations. So stylish!
Take the plunge! If you feel the need for instructions, you probably have enough old pattern instructions around that are similar enough to get you through making the garment. Sometimes I jot down my own sequence of instructions and I use old pattern instructions to help with making additional pattern pieces such as facings and lining.
