Context: I echoed the sea theme with the frame , using eyelets and cord to look like rope at the bottom . I had my MRI scan today - which was fine apart from the fact I had to lie flat on my back for 20 minutes and I do n't do flat on my back ! Due to a back injury when I was 12 I have a curved back and out of kilter pelvis and so it was hell trying to lie flat for that long . But tis done now and I await results .
