@coffeeandcake thank you. I tried to work out the bust apex on the paper pattern held up against her, but I think I just got it in the wrong place. I have revised the apex on the toile now and I'll see if I can aim the dart better at that.
@datcat23 interesting. I have never heard of a curved dart, very much still a beginner with all this. I'll have to do some googling as it sounds like it may well be the solution in this case. Thank you for that.
