Since I have had a Pfaff for many years I always use the IDT (walking foot) on all applications other than FMQ. It is fabulous. On my Juki I have to attach the walking foot...that said IMHO the walking foot/even feed foot is the absolutely best investment so your top and bottom fabric feeds evenly so you never have to worry about bunches or misaligned top and back fabrics. Using just a regular foot can cause uneven feeding of your top and back fabrics. That said, there are many people who do have superior sewing skills and don't need this foot.
