Sounds like you're all good to go! I'll repeat what others have already said...this is a fabulous undertaking; I so wish I could be a helper in a mission like this.
Mind you, I just took my first quilt class the other day. The visuals of the completed task helped tremendously. The teacher was barking out: "now make three strips this size, then 3 that size, etc. and all of us just couldn't get it without looking at the finished strip. With your language differences, this will be a challenge.
My only extra 2 cents to add...put a bit of humor in and all should go well.
Congratulations and best wishes for a successful outcome!
