Lots of excellent points-totally agree with these listed from above.
*I would expect is for the instructor to BE ORGANIZED, and/or have a helper that can take care of that for you.
*The instructor should be ready to go at the stated time of the class and all attendees should be in place. I hate it when a class is scheduled for 9 am, the instructor putzes around until 9:20 and then someone says "oh we have to wait for Mary ha ha she's always late". Start the class within 5-10 min of the stated starting time. Don't cater to late-comers. I have so many obligations that taking a class is a luxury
*I expect the instructor to be organized and knowledgeable about their subject, have nice samples, be fun and friendly, and come around to each person if only to say how nice their project is coming along.
*The instructor should insist that students have basic knowledge of their machine: please don't waste my time teaching one student how to insert the needle or thread the machine.
