I have one of the large scrapbooking totes like your Mom's. I think it came from Michael's and I really like it. I know some people found they broke theirs but so far mine is great. I pack it to the brim when going on retreat, but I do not use it for my machine. I store it back in it's box when not in use. I usually just carry my machine, but I have used the old fashioned suitcase trollies when at a conference where we had to take our machines to different buildings throughout the day. Might find them at a 2nd hand store for low cost. This is similar to my luggage carrier wheels.
