Tea cup pattern/practice

For the past few days I have started working on the tea cup for the boater hat. This is the first time I have worked with a large 3D form as far as crochet goes. I have decided to work from a pattern I have found on youtube and once I've learnt the basics I shall create my own pattern. I shall use a 6.0mm hook for this pattern as I am using chunky knit wool, however for future reference if double knit is needed I will need to reduce the size of the hook and take the advice of what the wool manufacturer places on the wool bundle.

Below are my first attempts of using the pattern. I am thankful that the youtube video shows step by step basics, however I am already noticing part of the pattern which will not work structurally for the hat. I may need to reduce the over all size of the cup so that it stays upright.  I have done 7 rounds so far and predict it will take another 8 on top of this to make the tea cup full size.
