First thing is to check with whoever is in charge of the class and get the skinny or fatty on what is needed for the class. If you need to take along a larger than 12 X 18 cutting mat you might invest in an artist's portfolio that is large enough to hold the mat. I have a craft tote that holds my machine and has pockets for the notions etc. and the fabric will fit on top. However this needs replaced so I am designing a project portfolio to take along with a new machine rolling tote.
