1/4" isn't always a 1/4". Using different machines can effect your end results.
OK, for taking classes, I usually only do a working piece ... one that doesn't have to grow or anything. I can donate it to my quilt guild as a charity quilt or something for our annual action.
I prefer to use my FW for classes. Then I either finish the project on my FW. Or I make something new on my home machine.
