I've been to a couple now and I try to plan on working on up to 3 projects in case I get tired of one and I can work on another. I get all the cutting done ahead of time if possible, keep each project in its own tote. Usually they will provide cutting tables and ironing stations for you to use. Bring your own rotary cutter, rulers, extra needles in case you break one, thread for each project, scissors, straight pins and anything you normally use when sewing at home excluding the iron. I bring my rotating cutting mat as its fairly small and I can cut smaller items on it instead of taking it to the cutting table.
