I know you MPix guys get so sick of this stuff, but I'm having a hard time with this. If I make a 4x5.5 postcard, should I size it to fill the page? Or will that cause the usual clipping of edges? What's the best way to do this so I won't have any white around my black images? Thanks so much, and again...I'm sorry!

Chelsea,

It is best to right click and select "Resize to Fill Page". You can then edit the layout of the image. The most important step is to preview the card in the PDF preview before checking out. 

Here is a blog post showing some sizing information: Post Card Sizing
