Lengthen the Sleeves 6" on Square Scarf Print

I found a great silk bandana scarf print that had a square pattern about 44 x 44” this worked out really well with the layout on the bias. This is my first test lengthening the sleeve so I left the concave shape for this sample is see how it would drape. 6” is about all you can fit into a 44” fabric. If wider there is more to work with obviously. What is nice is that if you like to push your sleeves up this works really well. In the images I try to show the sleeve down and pushed up.
