Here's the second reason I like Close to my Heart's paper packs, though I must admit I did not like it much at first.
See how there are 3 pairs? That's because one is the front side, the other is the back. Front or back, each pattern coordinates. This is not always the case with other companies. This gives me more options to use & can make layouts using the same paper pack look totally different, but it's OK to just use one side too! As long as you have one side that matches any side of your other 2 patterns in your kit you're good!
