First I'd do the research suggested to see if it's advisable.
Then I'd make a complete mini-quilt with the same materials and in the same manner as you have with the main quilt.
Next, I'd put it to the test .... wash and dry in the extreme conditions it might be put to. Yes, you might intend to always give it TLC, though what about the time it accidentally sneaks into the hot water wash. Yes, abuse it just as it might happen.
Then you'll know how it might stand up ... and whether you want to proceed! (and as you know, please be sure to let us know afteR!)
