One arrow for Rochelle.
Of course I cut the feather parts wrong.
I am not a math person and English is not my native tongue so maybe that's why :-)
But I solved it by cutting the first corner triangle,
flip it over right sides together, to the other side and cut the second corner triangle.
Clever me hahahahaha.
Although this is a block I would never make for myself,
I am glad I am challenged sometimes to get out of my comfort zone :-)
I will send the leftovers with the arrow Rochelle.
