First things first. whichever software you use keep in mind that the most important element of a scrapbooking layout is the photo or the photos you use. When you have picked out the photos then you can choose the embellishments, the frames, the elements and the papers.
1-Important: The colors must combine. Observe the photo and see which is the dominant color. Then choose the kit that you will use.
2-Don’t use too many photos one or two is fine and even better are several shots of the same theme.
3- Use the best shots and try to enhance your photo, if you are using photoshop go to- image- adjustments-levels and play a little. The most common mistake I see in layouts around the internet is moody pictures among bright elements.
4- Do not cut people or faces if you are not very experienced, better use a nice frame than a bad extraction. If you wish to do that, download some tutorials. There are even some filters that will help.
5-Play with texts. a nice word art and journaling will make your layout exquisite
6-Don't suffocate your layout. You don't have to use all the elements of a kit in one layout. It will look messy. Choose carefully which elements will help to enhance your work.
7-Organise your stuff by color or theme. Most of us have a huge amount of designs. I personally forget that I have a specific element and often I design it all over again.
8-Join a scrapbooking community for inspiration and ideas.
