KCmom's answers are spot on. I wouldn't load those pre-glued quilts unless you really don't like them. You need to get used to how your machine handles, first! This is why you always load a piece of muslin to practice on before you start on a quilt you've spent hours piecing. If you don't, your first LA'd quilts will probably be a mess while you're learning. Waste muslin, not a beautiful quilt top!
