Do you have some sort of tote? What kind of machine do you have? Most machines can tolerate being taken to a class in a carrier. I have 2 Tutto cases that I use. I have the Serger case that will fit my smaller machines (my FW, my Bernina 215) and a XL one to transport my larger machines [Janome 8900 (only to the shop for servicing) or my Singer 301]. I can even fit in some of my sewing stuff like my accessory case and sometimes my project.
I know there are other cases on the market that people swear by, but Tuttos are my favorite. They are not cheap, but you can find them at reasonable prices if you shop around.
