Jeremy, thanks for your best wishes, also the suggested fingering for C#. I found it didn't give me C# but tracking off your idea and looking for alternative fingering I found, using the online tuner, that XO XXO was spot on! Also, my flute was not accurately tuned to E (all holes closed), but was sharp (too short) Building a 4 mm extension out of blue tack (you may use yellow tack or pink tack in the States lol) tuned it spot on! Will add a wooden extension later.

Corie,
Congratulations on the flute! Half-holing is a technique that requires a lot of practice and experience. I am glad that you are becoming familiar with it and it will get easier and better as you learn to subtly adjust your finger depending on airflow.
First, some flutes are not particularly good at half-holing and are sensitive. I have one that is very tricky and have learned that block placement is critical on that flute. In fact, I have to adjust the block for the half-hole when I start to play with that flute. So, play around with block positioning. I have had to move the block back almost 1/16 of an inch behind the true sound hole to get a clean sound on the half-hole.
Second, you should not have to half-hole for C#. Try: xo xoo That should give you C#.
I would not mess with the tuning just yet. This might be a reason to tell your spouse you need to expand your collection....
