I contacted Janome today with accessories I would like to have for the 12000. Maybe if enough of us want certain items they will come out with them.
Janome did email back that the email was forwarded to the people responsible for the 12000.
I asked for:
A smaller hoop, maybe 4 x 4.
Acufil quilting hoops like on the 11000
A vertical thread holder (which I said should be included standard)
