Here are a couple of cards I made last night for sending to family members for Valentine's Day. I just used various bits and pieces of paper and embellishments from my stash. The base card is tan/kraft paper. I used some vellum to overlay the card base. In both cases the vellum design is a mix of envelopes.
Even when I use my brad template from Stampin' Up, my brads are crooked. I wish I coul find a way to line them up better.
