your new machine
my 2 cents would be to buy 2 flat twin sheets load them on your machine with batting between and just practice, circles. and squigglies until you get the feel of how fast you go and how fast your machine is sewing. you won;t be making feathers your first day. atleast i couldn;t.
its like riding a bike the first time you need to get your balance and be comfortable before you can do wheelies.
