PghPat ... there's no real instructions needed. Just put the foot on and start FMQing! It's just a normal foot change, except for the ability to change the toes!
So like three feet in one. I can't remember whether there were any specific instructions beyond what was on the boxboard packaging. Unfortunately your Florida LQS does not know about it, though any good Janome dealer should just have it in stock, and not require a special order.
Once you get it and get started ... we'll be here to help you continue on if you do have questions! FMQing is all about practice, practice practice .......... and then some more practice!!!!!!
Good Luck ... it is addictive!
