To get an idea of quilts you can make, you should look at the Missouri Star Quilt tutorials. I have found them very helpful.
As to their site format, at least you can see the collection by clicking on the pack. Some sites only have the pack with the top color/print and you can't see anything else.
I've made 2 baby quilt tops with 1 charm pack and a jelly roll (the falling charm tut on MSQ) and it went together
fairly quickly.
