Store the items that you only use occasionally in another corner, where they are not in your way. Make as much of your space as you possibly can. Consider buying utility drawer cabinets or shelves, which will keep your table clean. Make sure that you keep your craft room as tidy as possible. Keep your containers always ready that you use when going from craft show to craft show.
Nobody likes to pack the evening before.
Keep a couple of hooks ready on the wall and exchange craft items, as you move through the year and your crafts change. Make sure to clean brushes, jars and glue guns after you are done. This way they won't mess up other craft items or your desk. We all know that it is no fun to start crafting, when you first have to clean your tools.
