Yes, she says that hoops are not interchangeable and I have to use a BabyLock on my machine, brother on a brother etc. There is a 4" sewing space, so there's a 4 in hoop and a larger 6 x 7 hoop that is multi-positional. I asked what magna hoops were and if I could use any other type of hoop and she was a bit evasive, but again, she's a dealer so she gets paid to have pro-Baby Lock opinions. The 4" is 71 and the bigger one is 77.
She said that Babylock cards were best, and didn't say if others were an option. I'm hoping to have a chance to either talk to a friend in this area, or see a post about whether or not my machine can take PES files or cards. Looks like cards, even at all brands, are rather expensive. My machine did come with a few built in designs, so I'm hoping to have a chance to experiment soon.
