I am sorry to hear you didn't get good training. Sadly - not every dealer has good "teachers".
I too think a Regalia is a HQ machine. There are several FB groups dedicated to Handi Quilters, Do you have the Pro Stitcher as well? Several folks who own Regalias with the Pro-stitcher are members of the FB "Pro-Stitcher Posse" (which is a wonderful group with several HQ Educators as members). One other option is using an online instructor. I have known several gals that have taken classes with MK University . Another online resource if you have ProStitcher is "Adam So Fun" who is a HQ instructor and has many YouTube videos that are excellent for learning.
You could be bold and call Babylock directly !! Good luck
