I worked one of those events a little over a year ago. (I helped everyone with their machines and answered questions.)
You will have a great time. Really everything is provided and you will make a number of different items. The hoops , programs all the items they sponcer , is formated for all brands of embroidery machines. I use the Magna Hoop all the time and I love the target stickers. Really, anyone that has the chance to attend one of these events should go.
