Revival of a blue linnen jacket

Out for an adventure! This blue linnen jacket will always get vertical creases down the front and horizontal ones on the back when worn. After half an hour wearing, it looks like pulled from an old clothes collection.
Possible solution: I'll try to fuse some of this old African indigo onto it and quilt it. I'll let it stand half the way down like a shawl. Not the full width, this is just to show the beauty of the cloth my mother gave me when I was about twenty. I sewed an awful blouse, my work then was trial and error method, mostly error.

It is a "spoil it or save it".

With two cotton patches after fusing. I'll treat the sleeve cuffs in the same way, just have to get more Wonder Under, I used it up to the last scrap.
