Just an idea but my husband got a free cheapy piece of lugage on wheels. I gave it to DD 14 who takes her Janome Gem Gold in it to class. People always comment how nice a tote she has. It is black and has a white design on front. You might also check soft ice chests on wheels. I had a video camera for yrs in a soft ice box I bought at the grocery store. You don't want to know how many people wanted to know where I bought my camera case. LOL
I am glad you were able to find a good deal. Have fun at class.
