Weeding can be difficult if your project is detailed. Especially if you're working with Vinyl (which is sticky). It's easy to make a big mess with the vinyl as you peel it off of the backing sheet. You can create a "bounding" box (or a weeding box), but drawing a rectangle around your image in Cricut Design Space, then clicking "attach" to attach it to your image. Your image will then be cut with a large square around it. Which makes it much easier to weed since you are not dealing with as large of a piece of excess vinyl.
