Say Karen!
Could you post patterns of your jacket and a quick how to for us sewing newbies?
This idea of yours could solve maintenance problems in the long run beause the reader is built to last. One could have multiple jackets to suit the mood of the day. Or pop one in the washing machine and dress the reader with an other... we're pampering that thing like they were babies, might as well have a change for it. Glad they're not diapers though. Been there done that. I'm looking forward to be a grandpa although not too soon.
