This is one of those easy steps that can go pear shaped lol
Firstly, baste it, rather than pin, then you don't have to keep pausing to remove pins. I generally start at CB and try to go round in one pass. You may find that it 'sticks' when you go round the corner at CF, I keep a chopstick or wooden skewer at hand to sort of push the fabric under the presser foot if that happens.
Fingers crossed, deep breath, off you go
