Actually, the answer to that question is very simple. You need an album, page protectors, and pocket page cards (or paper that you cut yourself to size). That's enough to get started. On journaling cards you can put the story to go with the pictures.

Of course, if you want to decorate your pages, you can dress up this base with some embellishments like stickers, ephemera and stamps. You can make it as simple or complicated as you want. If you have time, then make it a party, but if you don't have that much time, little fuss is needed to make it a nice page.

Of course, if you want to make it easy on yourself, you can opt for the DLS Design Pocket Page Kit. The kit includes everything you need to make nicely dressed pocket pages. All you have to add yourself are page protectors of your choice and your photos of course! 

The Pocket Page kit makes it very easy and quick to create a page. It is very convenient that the cards in the pocket page kit are ready-made, so you won't spend time cutting paper. Everything from the kit fits together nicely and so you don't spend time looking for things together. You can choose a subscription where you get a nice kit every month to capture your memories. It is also possible to buy a separate kit and try out if a kit is something for you. Anyway, I really like how it works and it really makes memory keeping a lot easier and faster for me.
