Collection Packs are such good value. You get one 12" x 12" sheet of each paper in the Collection and usually this comes with one sheet of co-ordinating tags and/or a matching sheet of numbers and alphabets. With this amount of co-ordinating stash you are sure to come up with some amazing layouts and still have some left over to make embellishments, such as journalling tags or cute pull out tabs. The Stacks are also great value for money with lots of yummy papers all in one place. Why not try one? You won't be disappointed. I love the 4.5" x 6.5" Once Upon a Time Stack which I find great for instantly matting my photographs and I love the Basic Grey Pheobe Pack. Which is your favourite?
