Notice the brown border surrounding this scrapbook layout? This is done intentionally but not necessarily as a design element. Instead, the added edge has a practical purpose.
I have noticed that not all scrapbook printing companies are the same. What I mean is, not all printing companies cut their printed scrapbook pages the same when combing them into books. As such, I’ll often have significant variations between what allowance one company provides and what another does not.
The standard advice for digital scrapbookers to place all essential elements within the space 1/2 an inch from the edge of the page. All other details can go all the way to the edge, but consider anything 1/4 in from the edge likely to be cut off.
With this advice in mind, I like to put a narrow border on my pages. Anything inside the border should not get cut off. Anything under the border may. This helps me to visualize the space I have available to me.
Some scrapbooking programs have gridlines that you can lay over your layout creations that are not permanently attached to the design. For me, this is not enough to jump out at me, so I place my border on a separate layer in Photoshop Elements. Sometimes I remove the border before printing and sometimes I do not.
Consider adding borders to your layout for design purposes, or practical ones as well. Most often, the small border will be trimmed off.
