Think about a pocket. Think about an envelope. Think about a napkin or the corner of a bed sheet. This card sketch could easily be any of those designs.
Choose a patterned paper for the background, then offset the corner of a solid color or slightly patterned paper across the top. You don't want two busy patterns together for this one because it just plain won't look right.
Then use the left side of the corner piece for a phrase and the right side for some embellishments - or vice versa. The fun part is that it's completely up to you how it's decorated.
So now ... think about the variations you could do. I've already found some pretty denim patterned paper to make a shirt pocket, and a paper that looks like lace could make a pretty table cloth or napkin.
