That's a lot of cards for someone who does not generally make multiples. No, I'm not obsessive; absolutely not. Um, really.
Here's how I do it. I usually pull out a set of stamps and play around with different color schemes, tools, techniques, etc., to mix things up and keep from boring myself to sleep. I may make a couple of cards with one set, or I may make a dozen cards. Very rarely, I may make three or four of the same card, but usually, each one is at least a little different from the others.
Sometimes, cards made with the same set are very different, as with these two cards using Papertrey's Snowflake Serenade set.
The blue and white card is my favorite of these two. The colors make me happy (red just doesn't convey "peace" as well as blue does), and I love that Martha Stewart border punch. The blue gemstones are more harmonious than the gold beads in the red card because there are five of them rather than four...I really prefer odd numbers, and adding the snowflake let me add a fifth gem. They balance this card nicely.
What do you think?
