Making hoods for old STis

[Kango]

I have an old Cervelo that I upgraded to 11 speed. Just love the bike and can not retire it. Problem is I can not find replacement hoods for the 11 speed mechanical gears and rim brake DA Sti’s. 
Any idea how I could make new hoods. I think it will also be nice if they are custom formed to my hands. 
Any ideas?

Which series Dura-Ace? Friend of mine bought ones in December last year (ST-9001 Replacement Hoods), took about 3 weeks to arrive from https://farnearbikes.en.taiwantrade.com/
